Help! So i just had sex for the first time! And we did not use a condome!

Im 28 and i was a virgin until march 9th. I had just met this cute guy on march 7th. And so we had sex and we didn't use protection like we should have. it was my first time. It really hurt and after that I was bleeding a lot I guess I might have started my period. I think he came inside me. Just hope I'm not pregnant! I'm scared to death. I only just met the guy 6 days ago! I do like him I just don't know if I'm in love yet.

Sincerely,

dazed and confused
