So me and my boyfriend 3 weeks ago, did dry sex. He had his boxers and pants on and I only have my underwear on. He said he didn't ejaculate and he also disnt went inside of me. But the morning after that I started feeling a pain on my left side of my pelvis. 2 weeks after, i got my period. I know its not implantation bleeding because it was heavy and lasted for 3 days, i only got sotting on my last 2 days. But until now, the pain on my lower side of my pelvis is still in pain. im thinking this could be by constipation cuz I have it right now, but i also heard that i could be a sign of pregnancy, so do u think im pregnant?
