Hey everyone :) so my period was supposed to start last Wednesday (did have unpritected sex)but sometimes it does go a litter later usually 28-32 but I am now going on 37 days. I've been having lower stomach and back pain, breats are really tender and spreads under my arms, head aches, feeling tired, been peeing more and I'll randomly get nauseous. I took a pregnancy test on 29 days it was negative so I just waited figured I was just going to have my period later this month when still no period I took another one on 34 days still a negative. I have felt like my period was supposed to start before with light cramps and just that feeling but nothing. Does anyone have any thoughts if I could be or not? Any information would help. Thanks :)
