I had the full feeling my IUI cy that was

, and it went away by the time AF came, I believe - maybe a day or two later.
On this cy, I had it for a while - it really didn't resolve until maybe 8 or 10 weeks. My belly is big now, but I don't have that . . . heavy/crampy/bloated feeling anymore. That was not fun - I'm still not sure if it was the OHSS or pregnancy that gave me that feeling.
