I'm currently 13 days late for AF and have been testing every couple of days, but it's still coming up Neg. I've been getting headaches, nausea (very uncommon for me), slight cramping on and off since the day I was due and some breast soreness. I'm so confused because for the last 4 months (after stopping BC) I have had a spot on 31 day cycle. I've never been pregnant before so I don't know what my body is like when it is pregnant, but I do know I feel off. Plus I've wanted to eat everything under the sun (not sure if that's worth noting too).
