Being aware of your menstrual cycle and the changes in your body that happen during this time can help you know when you are most likely to get pregnant. See how the menstrual cycle works below.
The average menstrual cycle lasts 28 days. But normal cycles can vary from 21 to 35 days. The amount of time before ovulation occurs is different in every woman, and even can be different from month-to-month in the same woman, varying from 13 to 20 days long. This is the most important part of the cycle to learn about, since this is when ovulation and pregnancy can occur. After ovulation, every woman (unless she has a health problem that affects her periods) will have a period within 14 to 16 days.
