Please help me.

I and my husband separated this January, I don't have a job, my son is 8months old, and I just discovered I'm pregnant. I wish I could keep it but I can't because right now I can barely take care of both of us. I want to use the pill, can I still breastfeed if I take the pill? Please I'm in a very tight corner. please help me. I don't have anyone to talk to outside of this group.
