Scared, please help

Okay so me and my boyfriend had sex and the condom broke ( he didn't cum, and pulled right out) just to be safe I got plan b. Well a few days later we had sex again and when he started to cum inside me but pulled out quick! When we was out there was thick white stuff on the outside of the condom. But I think is was me cause I went to the bathroom and saw the same thing. We think we are okay. Do you guys think I could be pregnant?
