I'm WAY late to this party. First of all, let me be the very last (!) to congratulate you! It's so way cool. I won't gush on. But it's amazing.
I'm probably projecting all over the lot here, but I found that when I was pregnant I was SO sensitive to any lack (perceived or real) of affection on S.'s part. It made me resentful, I was always thinking "But *I'M* the pregnant one!" Granted, S. is probably way lower on the great-partner totem pole than your H is.
I think that pregnancy and early motherhood in general are times when you are ultra-needy (and maybe not so aware of the extent of it) and ultra-sensitive to any slight of caregiving.
May the rest of your pregnancy go as smoothly as possible - in my opinion, a baby girl is the biggest gift of all. No slight to you baby boy people, but my god, a little baby girl is the most amazing, awesome treasure.
