Scared of pregnancy!

Kay • I love to hold you close ❤️
So i just got done having sex and my bf had a condom on and he didnt sperm at all... and we fucked for about 15 mins and then stopped and when i got back inside I was bleeding a little bit and their was blood in my underwear ? Their was no sperm involved. What does this mean?! Im scared ! Does this mean i can get pregnant?
