I think everyones PCOS will respond differently during pregnancy (not sure, i havnet asked). And then the added pregnancy symptoms from hormones they dont tell you about wich also include more hair, acne or clearing up, etc.
Personally for me.. my belly got a lot more harrier

, and im still cramping like normal, and my hair is falling out even more and my skin is flaking like crazy

. Ugh.
It doesn't really "bother" me all that much. I just hope everyones different and its not really like this w/ pcos and pregnancy lol.
