Help! I literally have no idea

So I've done sexual things with a boy but we didn't have sex, but my actual vagina hole is itchy, I think I have a urine infection and my nipples hurt a lot when touched. I'm a bit scared he may have had precum on his finger before he fingered me but surely it's very unlikely I can be pregnant right? And I think he bit too hard on my nipples as I remember them hurting afterwards. I can't be pregnant, can I?
