So, it took us a couple of years, a couple of miscarriages, and a couple of rounds of Clomid to conceive our first child, Miss M. For my entire life, I did not have normal cycles. Wonky, weird, ovulatory, annovulatory, super long, super short, 35, 45, 60 day cycles, ovulation on day 20, 22, or worse...that was me. That was why we needed the Clomid--it helped me have normal cycles, and helped us quickly become pregnant. I would have preferred to get pregnancy naturally, but you do what you have to do. When it came time to conceiving our second child, we went straight to Clomid, and once again had success, for which I am so grateful.
I also didn't have periods for about a year after each child was born. They didn't return until I stopped nursing, more or less.
And now, at almost 42, when we are done family building?
I have perfect, 28 day cycles. I have textbook cervical mucus halfway through my cycle. I ovulate exactly on time. Every.Single.Month.
