For example, if your period starts on June 11th and your next period starts on June 7th, then your menstrual cycle is 27 days.
If the length of your cycle is different each time, try tracking your basal body temperature (BBT) to determine your ovulation.
For example, if your menstrual cycle is 32 days, then ovulation should occur on day 18. You are most fertile during ovulation, as well as the 3 days leading up to ovulation. If your menstrual cycle is 32 days, then your most fertile days are day 15, 16, 17, and 18. [5] X Research source
It’s important to take your temperature in the same part of your body each time for consistent readings. Keep your thermometer on your bedside table for easy access in the morning. Phone apps, such as Fertility Friend or Ovia, can be a good place to record and track your daily readings. You must have at least 3 to 4 hours of sleep to record your BBT. [7] X Research source You can purchase basal thermometers from your local pharmacy.
Keep in mind that any activity can throw off your BBT.
For example, if you record your temperature at a steady 97. 2, 97. 4, 97. 5, and 97. 3 °F (36. 3 °C), but then it jumps to 97. 9, 98, and 98. 1 °F (36. 7 °C), then the higher numbers indicate that ovulation has already occurred. The 1 to 2 days before the temperature increase were your ovulation days.
If you cannot tell by wiping your vagina, then put a clean finger into your vagina toward your cervix to get enough mucus to inspect.
Keep tracking the consistency of your mucus for 2 to 3 months so you can become accustomed to your cycle. Note that your diet, stress, individual hormone levels, and some medications can affect cervical mucus production.
