Am I pregnant?

Fi

I lost my virginity last Thursday to my boyfriend, we used a condom but I am not on the pill or anything, we then had sex again on Sunday and used a condom, he pulled out then came a few seconds later but is there a possibility that I am pregnant? I’m a very paranoid person and I feel like my mind is playing tricks with me to make me think I’m pregnant. My next period is due 17th feb according to glow. I’m 17 and I’m really scared I don’t want to be pregnant
