Im so scared

Im 19, Im on disability, Im depressed and living in a place that the sitiation scares me. I'm 4 weeks late for my period, I have taken 4 tests and I've gotten 2 positives, a negative and a faulty test. I don't know what to do if I am pregnant. I don't know how I would have gotten pregnant, I'm using a cervical cap and he uses condoms, I doubt he'd do that stupid thing of "stealthing". I can't stay living where I am but I haven't enough money, no family I can turn to and his family won't help because we're too young and I know his parents will push for an abortion but I juet can't do that. Adoption would kill me because in Ireland all adoptions are closed. I can't not know my child, or children. Multiples run in the family. I need help, and I have nowhere to turn.
