my "period pains" were worse than usual when i got my bfp. really, its not worth giving up hope ladies...
I usually had stomach cramps just for an hour or so before AF arrived, but this time it went on all day...and then well after I got my BFP.
Are you hot at night? That was an early sign for me, I was so hot, like a hot water bottle! I thought i was getting the flu!
Good luck!!
