If I had unprotected sex and my partner nutted (not in me) and we ended up having sex again like twice more, later on in the night (after the the rounds he peed and cleaned up his junk) could I still be at risk of getting pregnant ?

Thank y’all for the feedback. So another question... period was due to come yesterday, I have not gotten it yet but do have PMS symptoms. I had sex on the 29 of jan. Would this affect this cycle or the next ? Also, I really appreciate the feedback however, I dont appreciate the condescending tones. I use this forum bc my family is not open with sexual education and I’m on my own. So I am sorry if this seems like common knowledge but to me it is not.
