If this is the wrong group I apologize....but, any tips?

Hey all. I have some questions. Well, I’m TTC my Rainbow but I don’t think my man and I have sex enough because he doesn’t come around more than 1-2x a week. We do not live together. But upon getting pregnant, we were going to get a place together. No judgment please!! Well, today the thought cane into my head about Adoption. With my history of recurrent miscarriage (3 in a row), I’m scared of going through the same thing over & over. I’m just scared. Has anyone here Adopted a baby before? Do you need to be married? What was your reasoning? Any stories of giving up your child for adoption? Anything helps, I have so many questions!! Thank you!!
