Patience, I am far from knowledgeable about pregnancy style, but here is my take:
I like the dress. It's flattering, it looks comfortable, and you can probably wear it all through your pregnancy. It also seems like a good basic you could wear with leggings, cardigans, jackets.
The fit of the jacket looks good to me through the shoulders; I don't think I'm expert enough to say anything about the fit through the torso/over your baby. I don't think it's too trendy.
I like the jeans! I think the shorter length works for you. It looks nice with your heels. Definite keep.
I don't prefer the cardigan, I think it's less flattering than the other items you showed.
