Could I be pregnant?

Sarah • I`m 26 years old, not trying for a baby, but if it happens... I guess it happens
Okay, so I had sex with my boyfriend 3 days ago, and I got off my period the day before that. We didn't use any protection and we had sex 5 times. He pulled out every time and finished himself but I'm so worried. I'm super young, I CANNOT have a baby. Please give me advice as to what I should do!!!
