Me and my boyfriend were sexually active. 

I was a virgin, but then he put his penis on the very tip of my vagina.

He did not cum, and he did not cum anywhere near it. 

Although, he was not using any protection. 

Few days, later. I start to have my period, my stomach hurts so much and the blood coming out was less than before. 

I am so worried and i dont know what to do. 

Am i pregnant?
