pregnant virgin.

I am a virgin and was with this guy and then we got crazy. We were spooning at first and then he suggested that we pulled our underwear. Then, he closed my legs and was basically thrusting in between my legs and then came. And now I'm scared. I don't know if the sperm went into my vagina because I'm seriously stressing. I also felt cum on on his bed and my thigh so I'm thinking it must have sipped through...And this happened 7 days after my period.
