Hi there, I am CD35 today and 4 BFNs. I have a ob/gyn appt. Monday. I am feeling pretty crappy. My legs and back hurt, my lower abdomen has dull aches and pains and for some reason, this may sound weird, for like over a month I have had this weird, unexplainable twitching/throbbing/fluttering in my lower abdomen right in the front under my bb and over my vaginal area. So I think I am not pg but there is def an issue going on.
