I might be pregnant 😳

I'm worried that I'm pregnant. A few weeks ago I met up with this guy for the second time and he came inside me after promising to pull out. I didn't think much of it but lately my boobs have been super sore and swollen and I've been feeling sick. I'm on birth control but I don't take it perfectly. I've only met this guy twice I don't want to go thru this wth him. Please no negative comments I already know I should have been more careful I'm just really scared and need someone to talk to. If I am pregnant I'll most likely have an abortion, not because I don't want the baby but because I can't take care of it in my current situation
