Part 2/7:
The menstrual cycle is a complex interplay of hormones that leads to ovulation, which is essential for conception. Dr. Crawford emphasizes that the regularity of a woman's menstrual cycle is often the most significant indicator of ovulation. A consistent cycle, where a woman can predict her period within a few days, generally indicates that ovulation is occurring.
However, the situation alters for women on birth control. While they may experience regular bleeding, this is not a true representation of ovulation since hormonal contraceptives prevent it from happening entirely. Women often confuse regular periods on the pill with ovulatory cycles, which can lead to misunderstandings when they discontinue contraception.
