Adoption

So as far back as I can remember I’ve always wanted to adopt. Even as a little girl I would always carry around my baby doll and say that I adopted her. I have done sooo much research and read stories and met with people to talk about adoption. I recently found out that I can adopt a baby right now even though I’m 18 (i’ve always heard you had to be 20 something)

The thing that was on my mind was I’m pregnant and I don’t want to have twins and another baby but I also know that it takes awhile before anything happens. Should I go ahead and start the process or should I wait?
