Babydoll, there is nothing you can do to make your H come back but you CAN push him farther away by being pushy, pursuing and being emotional. I know you are pregnant and my WH left whenI was 7 months pregnant so I truly know how scared, sad and confused you feel.
NC is best for now. It sounds like you are open to him attending dr. appts (I was too). So aside from those, NO relationship talk AND NC. Just give some time and space, check out laws regarding child custody etc. just in case, but you have 7 more months before your baby boy arrives, and you should just keep yourself busy.
Something I did that I'm grateful for is make a baby blanket using cross stitch (I can't crochet or knit). Now my 8 month old boy loves to grab the animals on the blanket! But that project occupied my hands and gave me something to focus on, complete, etc. I recommend that you find a project like that!
