Now one really important thing to keep in mind, especially if you are trying to get pregnant or trying to avoid getting pregnant, is that ovulation is key to your menstrual cycle. The days leading up to ovulation are when you are the most fertile. Here's how to know if your ovulation schedule is on track.
1. Efficient ovulation occurs between cycle days 14 to 21 (again, with cycle day one being the first day of your menstrual flow).
2. The day of ovulation varies depending on your average menstrual cycle length, but it usually falls about midway between the cycle. Meaning, if you have a 30-day cycle, you should ovulate right around cycle day 15.
3. Ovulation should come on with a few days of clear, uncooked-egg-white cervical mucus (or vaginal discharge). Most women see this type of discharge for a few days leading up to ovulation. They typically see it when they wipe and just notice an increased feeling of wetness down there.
4. When you are about to ovulate, you should feel an uptick in your sex drive.
5. Some women feel a slight twinge or heaviness in the lower abdomen (where their ovaries are located) when ovulation is occurring, although not every woman feels this. Some women experience slight breast tenderness with ovulation.
6. Feeling sharp, stabbing pain during ovulation is not normal, and neither is seeing blood midcycle. (It's not normal to see blood at any point during the cycle, other than during your menstrual flow.)
And there you have it. Keep in mind that these rules are for women who are not on the birth control pill. The Pill changes your cycle in many ways, and the bleed you experience each month is a withdrawal bleed from not taking the pills, not a natural menstrual cycle.
If your natural menstrual cycle consistently does not look like what I described, then I would recommend making lifestyle and dietary shifts that support hormonal balance.
