How well do you know Aunt Flo?

Perhaps you’ve heard of her? Aunt Flo, A.K.A. your period or menses, marks the start of your menstrual cycle. If you’re trying to conceive, you should really get to know your cycle.

The average length of a menstrual cycle is 28 days, and includes menstruation, the follicular phase, ovulation, and the luteal phase. However, cycle lengths vary and many women have irregular menstrual cycles.

  • Day 1 to Day 5 is typically the menstruation phase. If you haven’t conceived in your previous cycle, low levels of estrogen and progesterone in your body will signal it is time to shed your endometrial lining and start anew.

  • Day 1 to Day 13 is also considered the follicular phase. Follicle Stimulating Hormone (FSH) and Lutenizing Hormone (LH) are telling your ovaries to produce follicles in preparation for ovulation.

  • Day 10 to 18 is the average time frame in which ovulation occurs and is likely to be your most fertile time. You can determine your most fertile time by using Ovulation Prediction Kits (OPKs), fertility monitors, or charting your Basal Body Temperature (BBT).

  • Day 15 to 28 is known as the luteal phase. The follicle from which an egg was ovulated begins to produce hormones that bolster uterine lining for an embryo to implant and grow. If pregnancy has not occurred, your menses will begin again at the start of next cycle.

If you have been tracking ovulation and suspect that you are not ovulating, it might be time to consult a fertility doctor. Contact our Patient Care Coordinators at 1-855-955-BABY (2229) or by filling out the Contact Fertility Doctors Near Me form. They can help you connect with a reputable fertility doctor who will help you determine if you are ovulating.
