How Do I Know When I’m Ovulating?

Status message

Active context: desktop

The exact time when a woman ovulates depends on the length of her menstrual cycle . Women with a 28-day cycle generally ovulate around days 13 to 15.

Signs of Ovulation

Paying close attention to your body can provide helpful information regarding your ovulation. Examining your cervical mucus can also give information regarding ovulation. Before ovulation, your cervical mucus may be dry or sticky. Closer to ovulation, it may take on a creamier consistency. Right before ovulation, your cervical mucus may take on a slippery consistency similar to a raw egg white.

Your basal body temperature (BBT) can also tell you when ovulation is approaching. A special BBT thermometer can be used to measure your temperature to the tenth degree. An increase of about 0.4 degrees Fahrenheit higher than your normal temperature can indicate ovulation.

There are also secondary signs of ovulation, which may not be present in all women in a consistent manner. These include slight spotting, abdominal pain, breast tenderness, bloating, and increased sex drive.

Charting Your Basal Body Temperature

Charting your BBT to detect ovulation is relatively easy. With your special BBT thermometer, take your temperature at the same time each morning and plot the temperature on a chart. You should take your temperature the first thing in the morning after you wake up, before you move around or begin speaking. Also, try to get up around the same time each morning, so your temperature readings can be as close in time as possible.

When you see a temperature increase of 0.4 degrees Fahrenheit, this can indicate ovulation. The shift in temperature should be the highest of the temperatures over the last six days.

After you chart your BBT for a few months, you should be able to see a pattern. This will allow you to plan the best days to have sex when trying to conceive.

Ovulation Predictor Kits (OPKs)

Ovulation predictor kits are at-home tests women can use to determine whether they are ovulating by checking their luteinizing hormone, which should surge sharply 12 to 48 hours before ovulation.

Unlike testing for basal body temperature, OPKs let a woman know in advance when she will ovulate, which allows her to plan intercourse accordingly. However, women who have irregular menstrual cycles, polycystic ovary syndrome (PCOS), or who take certain fertility drugs may experience misleading results.

The best time to have intercourse when using an OPK is the day of the LH surge and two days later. You may also want to consider having sex one day after that as well.

If you have been charting your basal body temperature and tracking ovulation, but still have not gotten pregnant, it may be time to see a fertility doctor. Current medical guidelines suggest that a woman under the age of 35 who has been trying to conceive for one year with well-timed intercourse, or a woman over the age of 35 who has been trying for six months without success should consult a fertility doctor.

i want to get pregnant before the end of this year, my menses started today 5th of Dec. 2012. wen is the best date for me to make love so i can get pregnant? pls i need reply fast thanks.

Hey Jessy,

I'd suggest picking up a box of Ovulation Prediction Kits. These are at home urine tests you can start taking around day 5 of your cycle to see if you are ovulating. When you get a positive result, it means you are likely ovulating soon. If you have a 28 day cycle, you should be ovulating between day 12-14, but not everyone ovulates on the same day and not everyone has a 28 day cycle. Good luck!

I 've been married for abt 13 years. And never conceived for my husband we separate because of that. So I'm now in a relationship for abt a 8mths now and I'm trying to get pregnant. And am not as yet it have me worried. Why I'm not conceiving. Please help me

Hi Savita - You should begin to monitor your cycle and determine which day you are ovulating so you can time sex to get pregnant. The start of your period is day one of your cycle. If you have a 28-day cycle you would most likely ovulate around days 13 to 15. You can use an ovulation predictor kit or track your basal body temperature to help pinpoint it. Best of luck, Claire

i had my period on 22nd September, 2011, when is my most fertile day to have intercourse to get pregnant. length of my cycle is 22-23days.

I have been having unprotected sex for seven years but have only had a guy get off inside of me once.I have not ever got pregnant. Do you think there is something wrong with me? My periods are sometimes irregular

If you are not ovulating, you need to see a fertility doctor for a complete evaluation. There are fertility medications, such as Clomid, that can help your ovulation. To find a fertility doctor near you, please use the "Find a Doctor" function in the upper right-hand corner of the page.

If you are over 35 and have been trying to get pregnant for six months or longer, or under 35 and trying to get pregnant for over a year, it is advised that you see a reproductive endocrinologist (fertility doctor) in order to have a complete evaluation and see what options you have. To find a fertility doctor in your area, use the "Find a Doctor" function on each FertilityAuthority page. Good luck!

i have been trying to get pregnant over 9 months,and i have irrgular cycle ,and i got pregnant 2 times from 2 years,and i have 29 years old,what can i do?

I do not menstruate monthly. A few years ago, if 2 months past, I'd walk in the drug store and pick up a tablet to let it come, and it would do such, and at times it wouldn't stop and I'd menstruate for a month or more, I'd have to take the same tablet to make it stop.Its been over 2 years and I have not used any tablets to let it start or stop, it does so on its own, but it comes like every 2 or 3 months instead of monthly. what can I do to let it come every month? I have been trying to get pregnant 6 years now and I have not been successful. what should or can i do?

Hi, I have the same problem as you have,,, plzzz advice me as well if u got to know something

Hi mk, If you are not getting your period, you should consult a fertility doctor to find out the reason. If you do not get a period, you do not ovulate, so it will be challenging for you to try to conceive. Give us a call at 1-855-955-BABY (2229) or email and we can connect you with a trusted fertility doctor in your area. Best, Kim

I have been taking birth control pills for yrs. but I stop taking it in almost 2 yrs.. Now I decide to have a baby. Would the age makes it harder trying to get pregnant when a woman is in her middle age and the husband is in his late 50's?. The length on my cycle varies bet. 25 days to 30 days. how am I suppose to know the right for ovulation. Does the ovulation kit works? Thank you..

As women age, fertility declines, meaning your chances of getting pregnant decrease. You should really see a fertility doctor, who can determine why you're not getting pregnant and recommend and provide fertility treatment. FertilityAuthority has a database of fertility doctors and fertility clinics across the country. You can search to find a fertility doctor or fertility clinic in your area.

i had my period on 20th august, 2011, when is my most fertile day to have intercourse to get pregnant

It depends on the length of your cycle but if its a 28 day cycle you prob ovulated on the 3rd sept. You ovulate 14 days before your next period. I hope this helps and baby dust to you.

Hi, I've had that egg like consistency and i had sex that day and then 2 days latter and i still am not pregnut.
I've gone to the doctors and nothing is wrong with me, my cervix is great, not narrow.
So what are we doing wrong? Is there something we can take to boost the sperm count? or make my eggs strong?

hey. just read your comment, i took zinc tablets for a different reason but noticed a clear physical difference in my sperm. i read the bottle and it says that it is used for improving sperm count. get your husband to try zinc. hope this helps.
