No harassment or judgement

I had unprotected sex with the same guy last week a few days apart. I have an irregular cycle and PCOS, so the fact that my period was already 10 days late when we first had sex was normal for me. However I did let him finish inside me multiple times. I know that in order to get pregnant you obviously have to ovulate duh. And obviously I haven't, or at least I don't think I have since that typically occurs 14 days after your period. I'm just a little worried about becoming pregnant and I don't have anyone I can talk to about it so encouraging words would be nice. 

And yes. I already know having unprotected sex is "bad" and I'm horrible for letting him finish in me and I should be thinkin about STI's, but we are both clean and we asked each other before we had sex. I'm looking for support.
