Help!! Opinions asap

So me and my boyfriend had sex for the second time ever this past week,the day after my period. Everything was going good until he pulled out and I was finishing and realized the condom was tore. I thought it was tore on the side,which it wasn't. And he jerked it off. He said the tip of the condom was hanging down and when he pulled the condom off in a hurry the tip tore off. I never noticed it was hanging though. I'm really not sure it even broke inside of me or when I was finishing him. He never came at all but I heard it's possible to get pregnant by pre cum,if the condom even broke inside me(not sure) but if that's the case,it wasn't tore inside me long bc we check it. I'm nervous because it's my fertile window now and I'm feeling weird and having period like symptoms. Any ideas???
