My boyfriend and I had sex this weekend like 3 times

I’m on the pill but its not that strong so he wore a condom. He didn’t cum in me when he came but for some reason my mind still goes to me being pregnant 🤦🏻‍♀️

I have brown discharge and i have gotten it before my period but it’s actually stronger now and I’m just scared because I read it could be that.

But he also didn’t cum in me and had a condom 🤦🏻‍♀️😅 ugh I also should be sleeping but I can’t
