I lost my VIRGINITY!!!!

I lost my virginity to my long distance boyfriend a few days ago. He actually came to my house and we did it!! He took care of my body and it felt sooo amazing😩 But is it normal for your vagina to get ... tighter? Even after you have done it several times? We had sex more then 4 times (lol) but it was hurting a little and my vagina was so sore. Is that normal?😂😂Also my period came after the last time we did it but he came inside me twice. Is it still possible I could be pregnant?
