On cycle day 41, was supposed to get my period the 24th, still nothing. Not even any spotting. Been feeling off.. diarrhea, a little soreness in my boobs, light cramping, headaches.. Was thinking maybe it's stress, but I haven't been stressing. Still getting negative tests. Maybe I'm one of the women that get negatives until they're like 6-8 weeks pregnant... any one have this happen and get a positive a week or so later?
