Delurking just to say rcr - I had cramping for several days before my BFP, and was totally convinced AF was coming, even though I don't remember having cramps BEFORE AF came before. So I'm with all the cautiously optimistic in wishing you luck!!
I'm cheering for you other ladies, too, just very busy with not-MDC right now. Hoping to see lots of BFPs and healthy babies here in the next few months!
