Serious dilemma

I’m a single mom of two with pcos. I’m currently living at home with my parents. My boyfriend and I are pretty serious, but we’re not ready for another child (He’s not my other kids father). I can’t afford to live on my own with my kids, as their father does not help out. I’m 100% against abortion, but I’m currently 10 days late for my period. I have not taken a test yet, I’m waiting until Friday. My pcos makes me late on occasion, but never this late. If I am pregnant, do I have this child and get kicked out? Or do I go against my beliefs? I’m torn!!
