Pregnant? 😩

Hey ladies! I’m sorry if I seem uneducated but when it comes to this stuff I sorta tend to freak out. Let’s start with the “ story”. So my boyfriend and I decided to have anal sex without a condom because a condom really hurts for me. It was day 2 of my period and while we were getting started his penis sorta slipped and touched my vagina. I’m not sure if it went in but I felt a push near my vagina. I ovulated about 9 days or 8 days later from the incident and I was on my period. My period is due in either 2-4 days, but most likely 4. I’m breaking out how i do usually. But at the same time I just feel as if I’m not going to get my period. It was a stupid mistake and will never happen again.
