Hiya Ticklish, I have PCOS and had three rounds of fertility treatment to conceive after trying naturally for about 12 months. I've been exclusively bfeeding and AF returned yesterday (I think due to Caty getting sick and having a reduced appetite?)....from what I've read/heard, PCOS can actually disappear after giving birth, that your body can return to normal sometimes...not sure what the stats are though. Have you thought about seeing an ob/gyn for ttc?
