It’s a tough situation, but you shouldn’t give away your baby out of guilt. Adoptions are rocky, and they adoptive parents should know that. Of course they are going to be sad, but it is your child and if you want to keep her you should.
It’s not to late to change your mind, but better sooner than later because at the moment as your only in your second trimester you can save the adoptive parents from preparing for the baby. Don’t feel guilty, the fact that you considered adoption for your baby means you want to best for her and don’t feel guilty for wanting to be a mother!
I hope whatever happens you are okay with your choice!
