As our practice is evolving, Jenni and I are helping more people learn how to chart their menstrual cycle. This is a skill I think everyone who has a uterus and ovaries should learn how to do. It can help you know when is the best time to conceive a baby if you are trying to, and, conversely, not conceive if you are trying not to. Fertility charting has many names: cycle monitoring, natural family planning, and menstrual tracking, just to name a few. I have a fantasy that every middle school kid learns this skill to help them know their bodies better and feel like they have some control before and as they start to experience their sexuality.
A normal menstrual cycle length is 21-35 days, with 28 days being the average. It is measured from the first day of bleeding (cycle day 1) to the first day of the next bleeding. The menstrual cycle is regulated by hormones produced in the brain and in the ovaries. These hormones fluctuate throughout the cycle causing many signs for us to notice; signs that can tell us if our cycles are healthy and when we are most likely to conceive a pregnancy during ovulation. There are several different things to pay attention to during the cycle to help interpret the signs of ovulation. We encourage people to pay close attention to their basal body temperature upon waking first thing in the morning, their cervical mucous consistency and the look and feel of their cervix (yes, it changes!), and the rise in the luteinizing hormone (LH) in their urine (often referred to as ovulation predictor kits, or OPKs). We have been using these three clues to help people figure out when the best time to conceive by insemination or intercourse might be.
There are many great books about cycle monitoring that give thorough explanations of all the signs to watch for while cycle tracking, please see descriptions in resource list below. These books have charts showing how to read temperature variations throughout the cycle and share some of the other physical and emotional changes to notice during ovulation. The Beautiful Cervix project online has great pictures to compare with if you are viewing your cervix using a speculum, as some people choose to do.
To help people track their cycles, Jenni and I created a chart for our clients to use. Please feel free to download and use this chart for yourself. MB Fertility Chart
