First time single mom

Hey! So I’m extremely excited for my baby! I found out I was pregnant yesterday and I’m on top of the world. The only thing stopping me is the father asked me to abort the baby. I can’t bring myself to do it it makes me sick thinking about it. But I’m scared to be a single mom. I only need my baby to get me through but this is a whole tiny person relyin on me. I gotta do everything myself. I’m 7 weeks and 2 days can I have some advice or tips on what I should do to make sure me and baby are healthy? Any advice helps right now
