Okay, so my periods, for the most part are regular but come March, it came on the 3rd like usual but then again on the 30th, I figured I was because Feb is a short no the, well, my predicted period tracker said I should start on the 26th of April and I never came, it said today I'm now 7 days late, I've been having headaches, cramping, mood swings, my nipples will tingle, slight soreness in my breasts, and I was feeling off...like my mind couldn't think right, I took a test this morning and it was NEG!!! Im not sure what's going on! My periods are never late like this, we are trying to have a baby but I'm just so confused now!! Any suggestions???
