might be pregnant

I've been fucking this guy since Friday. We aren't really into each other relationship wise we just like to have sex. We did it today and the condom broke. He swore up and down he pulled out. And if he didn't wouldn't I see stuff coming out of me? Today was the last time because he's in love with this girl. It was just for fun anyway. I'm not salty. I just don't want to be pregnant.
