Sex and Pregnancy

So I had sex and I think I may be pregnant but from research, I’m seeing it may be too early too tell (a little over two weeks since intercourse). I’m hoping someone may relate to my story and tell me whether this is how they ended up pregnant. So we had sex and he pulled out and wiped his penis. But we went to sleep for a little afterwards but had sex again without him peeing in between. It was maybe 4 rounds of us doing so but we slept in between each cycle and he pulled out every time he orgasmed. Do you all think some sperm would have came inside of me as precum ESPECIALLY with us having slept in between the rounds?
