I am 18 years old and had unprotected sex last friday and my period was supposed to start Wednesday. It did start on time however there's very little blood but more brown discharge maybe... It's been three days and its barely there but my period usually lasts 5 days. I had the normal symptoms and everything just a weird period. What could it be?
It's possible that you're having implantation bleeding, but it seems to me that it's just your body reacting to unprotected sex. Sometimes that happens, I suppose!
You're fine....dont worry
