Ok so, I had sex today and I went to the bathroom a little after and there was a bit of blood like just a little bit and then i went to the gym an hour later it’s only my second day of going to the gym so it’s a new thing to my body anyways I ran just like yesterday and did other workouts and thing. Anyways I got home and I went to the bathroom and there was blood like actually bleeding. Not a ton but like a lighter period. Like a flow. I have had sex a lot recently and just before my period like a day before my period I had sex and he kinda came in me. I’m on birth control tho!! And my period came! I just got off my period on Friday and then it came back Saturday but only for a few hours then it was completely gone after that until today. Could I be pregnant what is this?
