Having pre cum on your clitoris

Today me and my boyfriend tried to have sex but everytime he was trying to put it in. It hurt to much. He had some precum on his dick while he was rubbing my clitoris. After I got dressed and went home I saw blood in my thong. Can rubbing my clitoris with his dick while he might still have precum. Can it make me pregnant and how soon After should I take a pregnancy test. Thanks all. I know it sounds stupid but I'm worried and just want to know. No bad comments please.
