Worried.. Toxic relationship

I don’t know where to start, but i’ll just have a shot at it. I’m currently in a toxic relationship. It’s not great, we hit a year next month and it’s not the same anymore. I don’t want to go too much into detail about it, but just know it’s not healthy and i’m trapped in it. I told him not to finish in me and he did anyways. He took the condom off without me knowing. My period was due 2 days ago and it still hasn’t came. I always have regular periods. I have my nip nops pierced and they’ve been healed for years and i’ve never had any issues with them. Yesterday they started hurting, like just a shooting pain through them and i don’t know why, same with one of my breasts as well, just shooting pain through it. This morning i wake up and the same thing, it just hurts. They’re not infected, there’s nothing coming out of them and they’re not red or swollen any. I’m cramping as well. I know these both are signs of both AF and pregnancy. But my breasts and nips don’t hurt when my period is coming or is around. I’m worried I’m pregnant. I don’t want to be at all. But the state i live in abortion is illegal, and i personally don’t feel comfortable getting one anyways. and i physically can’t bring myself to carry my child for 9 months and give it up for adoption. I’m just not sure what to do if I am pregnant. I know first step is finding out for sure so i’m getting a test today, i know my period is only 2 days late but if it comes back negative i’ll wait a couple more days and retake it. What do I do about the relationship if I am? He’s just going to trap me more…
