Timing Sex to Get Pregnant

When you are trying to conceive, there are certain times in your menstrual cycle when you are more fertile than others. Fertile days in your menstrual cycle occur around the time of ovulation, when your ovaries release a mature egg for fertilization. If you are trying to get pregnant, it is important to plan sex during your most fertile days.

Fertile Days in Menstrual Cycles

Fertile days vary from woman-to-woman, depending on the length and regularity of her menstrual cycles. Women are most fertile during ovulation, when a woman releases an egg to be fertilized. For women with 28-day menstrual cycles, ovulation usually occurs between days 13 to 15.

Once an egg is released, it can be fertilized for only 12 to 24 hours before it dissolves. Sperm, on the other hand, can stay alive in the body for 3 to 5 days, making a woman fertile for about 5 to 7 days.

For more information on ovulation symptoms, read: How Do I Know When I'm Ovulating?

Best Time to Have Sex to Conceive

Because sperm lasts several days in the human body, and a woman’s egg only last a maximum of 24 hours, the best time to have sex to get pregnant is a few days before ovulation should occur. Couples should begin having sex five days before a woman will ovulate and one day after ovulation. Couples should try to have sex at least every other day.

How to Detect Fertile Days to Get Pregnant

A helpful way to achieve pregnancy is to schedule sexual intercourse slightly before and during ovulation. In order to make the most out of each session of sexual intercourse, it is important to understand signs of ovulation so you know when you are ovulating. This will help you plan sex accordingly to help you get pregnant.

  • Changes in Cervical Mucus. Cervical mucus can be an important indication of ovulation. Before ovulation, cervical mucus is dry and sticky. As ovulation comes closer, it may take on a creamier consistency. Right before ovulation, cervical mucus tends to take on the consistency of a raw egg white and may become more slippery. Charting your cervical mucus can be helpful because it allows you to spot patterns from one menstrual cycle to the next.
  • Charting Basal Body Temperature (BBT). Charting BBT . Charting your BBT can help you detect patterns of ovulation. You can buy a special BBT thermometer, which detects temperature to the tenth degree. Take your temperature the first thing each morning. You can detect ovulation by an increased temperature of 0.4 degrees Fahrenheit, which will usually be the highest temperature over the last six days.
  • Ovulation Predictor Kits (OPK). Ovulation predictor kits are at-home tests that allow a woman to predict when she will ovulate. The test works by measuring the luteinizing hormone. When the LH rises sharply, ovulation should occur in the next 12 to 48 hours.
  • Physical Signs of Ovulation. Physical signs of ovulation may vary for each woman, but may include light spotting, abdominal cramping, breast tenderness, and bloating.

I think you put a lot of useful information into your articles.

A lot of women don't think about the days leading up to ovulation. Good job.

Thank you, I will share this information.

my menstral cyle is 33days, so when is my ovulation . i,ve been trying to Conceive again after i had miscarriage in April 2010. Thank u

When is my fertile dates in 33 days cycle

When to be pregnant with 32 days cycle

Hi Jay, Assuming you have regular cycles that come every 32 days, you might ovulate around day 16. You can purchase an ovulation prediction kit over the counter to be sure. Best of luck! Kim

Not halfway through, so if you consistently have a 32 day cycle then day 18, not day 16, would be when you ovulate. It's a good idea to have sex daily beginning days before then until one day after you ovulate.

my boyfriend and i have been trying to have a baby fo r more than four months now.
both of us are in our early twenties and we are healthy and in a happy and loving relationship

he thinks i cannot get pregnant but he smokes a lot and i think that is the reason y we cannot conceive as yet

plus i have a 21 day cycle and it is had to sheck can any one pleae hel p me because i dont want to loose this man and the relationship we have

I have heard that smoking ( I assume you mean Marjiaunna) can cause sperm problems. The sperm speeds can slow down or decrease in amount. This is something you have to research. Also when you say trying, what have you done? You say you have a 21 day cycle? Is that an average? Also do you check cervical mucus? Basal temp? Do you know the day you ovulate. I am in the process of charting this information for the next few months. Most couples who try are not successful right away. There is only a 24 hr window in which a sperm can implant an egg. However I am responding to your post mostly with concern. You say you do not want to lose your boyfriend based on having trouble getting pregnant. However it has only been four months! I hope he understands how difficult it is to get pregnant. I also hope he understands his smoking habits do not help. I am 25 years old in a relationship with a person... We both would do anything to help the process. I hope everything works out.

i'm a 30 year old man, engaged to my amazing 20 yr old fiance, we've been trying to concieve for about year now, and still no luck.
i know that shes had quiet a few miscarriages, and doesn't have a child yet. Although i do have a beautiful 11 year old daughter whom will be 12 in july. However i grew up being the only child and would like my daughter to have a sibling..... to get to the point. Back in 2003 i had a major car accident that pretty much distroyed a major vertabre in my lower back that makes my lower half (legs, feet, kidneys, etc...) function....
See i had my daughter before my car accident and well i was just wondering if the accident that i had would have any misfuntion with concieveing a child. Maybe it messed with my sperm count or something. I honestly don't know. I don't want to lose what i have with her, and what she wants is to have a family....
If theres anyone that can help please let me know.
Thank you\

It could and cannot be, but to every problem there's an answer.

What I can advice you is to go see a fertility specialist and an IVF clinic. they would have many ways to see your goal.

I have a 3 year old daughter but I have lost 2 pregnancies before her and 2 more after her. now I'm trying to get pregnant too but nothing yet

Your fiancé can be blocked from a scar tissue of a previous miscarriage like me and also from Factor V lieden. she should get that checked. I have a day surgery to remove the scar and now I just have to try and take vitamins and after pregnancy shots.

my husband and i have been having sex for 2 years now and we have not been able to conceive. His job requires him to be away from home, and sometimes i stress about it. I don't know if stress is the reason why we have not become pregnant. I have done blood test, x-rays, ultra sound, urine test, pap smear and i am fine. My menstrual cycle is normal. I'm really getting frustrated that i may not be able to have kids.

I've pretty much tried everything. gone to the doctors and have ultra sounds n wat not n for the second yr of tryin to conceive it was very stressful. and now were just letting things flow =D. we've been together for 6 yrs now and We really want a baby and maybe im not doin something right. my menstrual periods r normal n i have a 39 day cycle. and i just had my last period a day ago, do hopefully this time it works. =p

Im 31, been prego twice. one was a tubel and one the doctor said it wasn't growing. My husband and I have been trying for some time now, but are having a problem. My cycle ranges from 30-32 days. I try to watch the vaganal mucas that you are supose to watch. when it is an egg white substence my husband and I have sex and after but still no baby. This month I started on Dec. 16th or 17th ended on Dec. 19th or 20th, but then started bleeding again on Dec.24th-25th. What is going on? Is something wrong with me? is it a sign that there is a problem?

Hi Angel, if you have been pregnant twice and have lost both pregnancies, it is probably time to see a fertility doctor, also known as a reproductive endocrinologist. You can find one in your area by entering your zip code in the "Find a Local Expert" box on every page of FertilityAuthority. The fertility doctor can run a whole battery of tests to determine why you are unable to get pregnant or are are having miscarriages. Good luck!

Im in my late 20s I have a beautiful daughter who's 3 yrs old, and a wonderful husband since 2006.

I have lost 2 pregnancies before my child and 2 after. I found out that all my scars had blocked me and ever since my last miscarriage till January I wasn't able to get pregnant.

In January I had my day surgery to remove those scars and now im trying but no success.

When is it the best time to have sex to get pregnant, if im a 28 day cycle???

im 53 yrs old im trying to get pregnent my periods are 3to4 days but their irreg. i think do i have to have a papsmear to see if im ok. and to see if everything is ok. ty

thk u so much for this article. i have learnt so much. i have a 25days menstural cycle so when is my ovulation period cos i 've been try to get pregnant for two months now. pls reply.

Not everyone ovulates halfway through their cycle, but you can purchase an ovulation prediction kit and begin testing around day 10 of your cycle. You will see a positive test when the hormone surge is detected indicating you are ovulating.

Good luck!

hi i am trying after two yrs of being married to have a baby and i cant seem to calculate right or im doing something wrong. can someone please tell me what i can do

Hi Tonia,

Can you tell me how old you are? Typically if you've been trying to conceive for longer than one year with well-timed intercourse and you are still not getting pregnant, you should consult a fertility doctor. Give us a call at 855-955-BABY. We'd be happy to help!


ok first i was told i could not get preg. at 38 i went for a test then put liquid into my tubes (it hurt) they told me sometimes that could unblock my tubes and would help all by itself. (WELL, IT DID!! ) I GOT PREG NATURALLY AT 41. I WASNT HAVING SEX FOR ALMOST 2 YRS OTHERWISE I PROBABLY WOULD HAVE BEEN PREG SOONER. anyway..... my 5y old son begs me for a sister daily and im only child so i know how lonely it is. so im going to try to get preg. however i didnt have my period for almost 1.5 yrs then all of a sudden i got it again a few months ago it is not regular like every 45 days (i have always been irregular going a year w /out even when young) i thought i was in menapause till i got my period again. i would really like to get preg w/out ivf. when is time?

Hi there,

You might consider charting your Basal Body Temperature, but I have to say it is probably in your best interest to get a full fertility workup with a fertility doctor. As we age, we tend to have problems with ovarian reserve (egg quality and quantity) and greater risk of miscarriage.

I wish you the best of luck! Feel free to give us a call at 855-955-BABY if you'd like information on a fertility doctor near you.

Hi there, In order to have a child of a particular sex, you would have to go through in vitro fertilization (IVF) with gender selection. Give us a call at 1-855-955-BABY (2229) and we can connect you with a fertility doctor who specializes in gender selection. Best, Kim

last year i had a miscarriage at 6wks and m an average of 30 to 31day cycle. We are in a long distance relationship and my last period waz 14feb we met and had sex on the 4th of march which was cycle day 19. Is there any chance for me to get preg. I really want a baby and i am getting impatient to wait 4 my p. I wil only be with my boyfriend after 4months and cnt wait that long

Hi Norie, It is possible, though if you ovulate regularly, you might have had sex a few days late. Only a blood pregnancy test will be able to tell you for sure if you are pregnant. If not, you should try using ovulation prediction kits (OPKs) from day 10-day 15 of your cycle to see when you are ovulating. Best of luck! Kim

we are newly married

Hi Austine, The best way for you to determine the best time to have sex is to use an Ovulation Prediction Kit (OPK) or chart your Basal Body Temperature (BBT). Either of these methods should tell you if you are ovulating and your peek window of fertility. Best of luck! Kim

Hi, my periods are irregular sometimes I dont come on for up to 4 months me and my boyfriend have been trying for a baby but had no luck, isit because of my irregular periods why im not ge tting pregnant?
