No period..

I'm 2 months pp and haven't gotten a period. No signs. Nothing. My fiancé & I have had sex. He used the pull out method & has cum inside. I know I'm stupid for doing so but don't judge please. I'm not breastfeeding I stopped at 3 weeks. Should I have gotten my period? What are the chances of me being pregnant again? Please don't judge, I only want advice. Thanks!
