However, they may still become pregnant if they have ovulated early or late in their cycle, as sperm can survive in the body for several days. Ovulation and the fertile window can change from cycle-to-cycle, but they may also alter with age.
Fertility naturally begins to decline in females from 35 years of age onward. Some medical conditions, such as endometriosis or polycystic ovary syndrome, also make conception more difficult. Birth control pills aim to prevent unintended pregnancy. The pill prevents pregnancy by releasing synthetic hormones that stop ovulation from occurring and the uterus lining from thickening. So, even if the ovaries do release an egg, a fertilized egg would be unable to implant in the wall of the uterus.
The pill also thickens cervical mucus, making it harder for sperm to reach an egg. According to the CDC , the pill is more than 99 percent effective with perfect use but only 91 percent effective with typical use.
This means that, with typical use, around 9 out of women would become pregnant in a year of taking the pill. Women who track their fertile window with the aim of getting pregnant should see their doctor for preconception planning.
As well as identifying barriers to conceiving, a doctor can advise on the use of folic acid or prenatal supplements to encourage a healthy pregnancy.
