I'm becoming quite a regular, but my brain's got so many questions and it won't leave me alone 'till it's answered. I went to my gyn/ob in January because after the birth of my baby in August last year I still didn't have my period back. He said it's probably stress, etc, etc. He did a vaginal sonar and said that everything looked fine, just that my womb is lying backwards. Now I want to know - if I had PCOS would it have shown on the sonar? Everywhere I read about infertility I read about PCOS and I've noticed some of the symptoms like the hair growth and (since August) irregular menses. When would be the best time in a cycle to go the the doctor and have tests done?
