So as of today i am 2 weeks late on my period. I don't normally think anything of it but this time is different. I have a small pain on both my left and right side right below my belly button when i bend or sit down and it forces pressure down on my pelvis and have been having some slight cramping. I'm a little unsure of what it could be. I have never experienced it but It's quite uncomfortable. The pressure pushes down from my pelvis into my groin . I've been nauseous the past couple days but nothing more than that along with breaking out in acne which i haven't had a problem with in quite some time. Any ideas?
