sarah,
hi! i've been lurking, but your post is sort of similar to my experience, so i thought i would add. i've been TTC for almost 6 months. Went off BCP in feb and cycles have been approx 45 days. I've yet to see a pattern on FF. After BCP, i gained 20 pounds, so i went to my OB. Got an u/s and after i told the nurse i was there b/c i was afraid of PCOS, she told me my ovary was full of cysts (approx 17) I had to wait 2 weeks to talk to my OB and when i did, i expected him to confirm PCOS. Instead, he told me they were follicles, not cysts, and my blood and hormone levels indicated i did not have PCOS. I still have a long cycle, but doc is adamant that i do not have PCOS or any other hormonal problem. I understand how you feel about not understanding test results (or getting the wrong ones)

Good luck!!
