TMI at the end

So I've been dating a guy for abt 3 weeks now. Over the course of the time we've been talking we've had sex and twice, one time right before my period and a day after it ended, we had unprotected sex. I've been on the pill for about two years and he pulled out.

Just for a little backstory this past week has been rough. I still live at home with my parents and I'm on their, my mom's, insurance. She's a nurse and the insurance is wonderful. Anyways because of the fact that I went to see an adult doctor I had to/wanted to discuss what we talked about when I was there. She knows I've been seeing this guy but not that I'm no longer a virgin. When I told her one of the things she said was, 'when and how many times did you give this up'. Now she knows and she'll hardly look or speak to me.

Back to the earlier topic, it's been a couple weeks and my period a couple days right after we had unprotected sex was very light. Normally when I go to the bathroom, before having sex, I would have white discharge in the toilet every once in a while like when I'm ovulating as well as just a small ache or tiny pain in my vagina. I had it the other day. I just went to the bathroom and only went pee but there was something else in the toilet. I couldn't tell if it was brown discharge or like some poop that I could've not noticed. I'm terrified that I'm pregnant 😭😭😭 pls somebody help
