help please!!! I’m 16, and me and my boyfriend had sex over a month ago. My last period started may 10th and was super light , and only three days. I was thinking maybe it’s implantation bleeding? It’s now June 10th and idk why my period isn’t here yet and it’s kinda freaking me out. We used a condom and I’m on bc, (sometimes we don’t use a condom, so I can’t be 100% with that but i think we did) BUT also i was taking melatonin to help me sleep at night which i heard makes bc less effective ! I don’t think i really have pregnancy symptoms though, no nausea or headaches or really aches anywhere. Please help!!
