Know your body
A recent survey revealed that only 27.5% of Ivy League students were able to correctly identify when a woman is most fertile during her menstrual cycle. This page can help change that.
Find out in this section:
- What happens during your cycle.
- How ovulation is an important function of your body and the risks associated with suppressing it.
- The signs that show when you’re fertile.
If you’re like most women, your monthly cycle is not “average.” Only 5 to 10 % of us have an “average” and “regular” 28-day cycle.
Whatever the length of any given cycle, which starts the first day of your period, it is composed of several distinct phases. These phases are regulated by hormones, triggered by your brain. The cycles are all related to the most important phase: ovulation.
When you ovulate, an egg is released by your ovaries. It’s only when an egg is present that you can get pregnant. If the egg is not fertilized by sperm, it will only live 12-24 hours. Since sperm can live up to 5 days, intercourse within 5 days of ovulation may result in a pregnancy. That’s why it’s important to know when ovulation is approaching and when it actually occurs.
These days are clearly signaled a few different ways by your body. Once you learn to recognize these signs, you can know with certainty any day whether you could get pregnant or not.
Read why ovulation matters below or see how you can know exactly when you’re fertile by reading the clear signs of your body.
Why ovulation matters
Many birth control methods work mainly by blocking ovulation through the use of synthetic hormones. These methods include:
- The Pill
- Vaginal rings (Nuvaring®)
- The skin patch
- Shots (Depo-Provera®)
- Hormonal IUD (Mirena®)
Your ovulation is a healthy and normal process, not an illness to be cured or suppressed with drugs. The effects on your body of blocking ovulation go far beyond just preventing pregnancy. Studies show how it impacts you and your relationships:
- You have a natural intuition for good genetic matches for you. The Pill can rob you of that ability, as one study shows. A good genetic match for you is someone who has a different genetic make up from yours or that of your family members. In fact, when you’re pregnant, your body produces an hormone that makes you feel closer to your family. Since hormonal contraceptives like the Pill make your body think you’re pregnant, you’re more attracted to men who have a similar genetic make up to yours—men who are not a good match for you. It’s a bad love potion: the guy you fall for while taking the Pill might not be the guy you fall for when your body is functioning naturally. If you fall for a guy while you’re on the Pill, you might suddenly find him a lot less attractive when you quit taking the pill. Awkward.
- Women on birth control give up the invisible power of their natural pheromones to attract men. One research study showed that men find even supermodels on hormonal contraceptives such as the Pill less attractive than average women who are naturally ovulating. In fact, a woman’s physical attractiveness actually increases at the time of ovulation. Another study showed that women who were ovulating even earned much higher tips than those who weren’t (just saying). Watch a video on this interesting phenomenon.
The good news is that blocking ovulation isn’t necessary to avoid pregnancy when you know how to read your body’s clear signs of fertility.
When are you fertile?
With training, you can learn to accurately read and chart the signs of your body. Your knowledge will give you as much control over whether you get pregnant or not as most contraceptive methods. The rate of success in avoiding pregnancy is 99.5 percent, higher than real women get using the Pill.
Several different signs show you exactly when you’re ovulating and when you could get pregnant:
- One of the most common signs is the discharge of mucus. You can feel a wet sensation once a month that lasts a few days. A yellowish or clear discharge will appear when you wipe yourself with toilet paper. This discharge is a sign that ovulation is near. The color and texture of the mucus tells you exactly when you are going to ovulate.
- Another sign is the temperature of the body, which increases and remains higher after ovulation.
- Around the time of ovulation, the cervix is positioned lower in the vagina, and with a bit of guidance you can learn to tell the difference on your own.
- Right around the time of ovulation, two key hormones are produced: luteinizing hormone and estrogen. These can be detected in your urine with a simple at-home test.
