I need advice!

Ok so my husband and I are expecting a baby feb 9, well he just graduated from Navy basic training and he's about to ship out for AIT he wants me to move with him to Groton Connecticut but I am living with my mom in Alabama right now while he's gone and she's my safety net considering 1) I've had a miscarriage at the beginning of this year 2) this is my first child and 3) I am only 19, but I really want to move with him but I don't think it's what's best for the baby but I want him to be apart of my pregnancy and he wants to be there what should I do?
