Could i get pregnant from this?

Abby

So my boyfriend and I had unprotected sex on 10/21. I have been dealing with an ovarian cyst since then. I’m supposed to start my period today. We used the pull out method and he didn’t even ejaculate into me at all but into a towel. He said he felt it before it came out so that’s when he pulled out. I’m very very worried that I will miss my period and get pregnant from this. What happens if I don’t get my period today? I’ve been spotting but was told the cyst can cause that. Please give me hope that I am not going to get pregnant from this. I have been taking the pill regularly for months
