Pregnancy Scare... help!

I had posted the other day about me thinking I’m pregnant. Well here’s an update.

Me and my boyfriend last had sex on January 24th (I only remember this cause it was our anniversary) and my last period ended the 21st. I use birth control pills so my period has been pretty regulated for the past year-ish. Sometimes a day or two late or early. I have always had irregular periods but it’s better with the pill. Anyway, We used a condom, it broke, so we just said screw it and kept going. *TMI* but He pulled out, and I’m sure he did it on time he always gives himself enough time for me to continue to suck him off and then he’ll cum (not inside me).

Well I’m now 5 days late on my period. I had some brown spotting last night and very very mild cramps. This morning just a little bit of spotting and some back pain. Usually I will have horrendous cramps two days before. And this time it’s just really weird? Like I’m sure it’s just cause I’ve just been really stressed out with school and work and our relationship has been rough but now that I’m 5 days late, I have been terrified. I’m 18, turning 19 in March. I still live with my parents and they both have told me before that they’ll kick me out if I end up pregnant. The past couple days I have been so scared, and I have given myself until tomorrow to go get a test. What are y’alls thoughts?
