T.E.
I also had that same problem. After giving birth to my son we wanted to wait awhile before we tried again. When he was 3 we started trying, he is now 6 and I am finally pregnant with our second child. At first I had what is called Polycycstic Ovarian Syndrome, which is just basically I had cysts in my ovaries which was causing me not to have a period. The doctor gave me some medication for it and that was fixed but still no pregnancy. So he put me on fertility medication. That didn't work either. My husband and I went through a VERY rough patch in our marriage and I ended up losing 25 pounds and low and behold 2 months later I was pregnant. The doctor had always told me that if I lost a little weight that might help and it did. I'm not sure, and being a woman myself I wouldn't even dream of asking, but I know in my case after I had my first child I packed on quite a few pounds. Hope that helpped some.
