I think you are correct that the problem then was "hormonal imbalance". The pill is effective at controlling symptoms, but does not correct this imbalance at its root cause.
It is true that fertility
varies during the month. Your most fertile days, assuming you have a regular 28-day cycle, are approximately days 10 to 14. (this assumes that you ovulate on about day 14.) when you ovulate, the egg does not last very long; in contrast, sperm
can hang around in the vagina for up to a week, which is why the days before the egg is released can lead to pregnancy
Whether to get further hormonal evaluation at this time depends on several things, including your age, whether you are overweight
, and whether your cycles are regular. If your body is at a healthy weight, and another hormonal imbalance is present, i recommend treatment with bioidentical hormone therapy
, which even in low doses can enhance fertility.
