Is he protecting himself or is this a bad sign?

Backstory: we found out we were pregnant in March after trying for several months. We were very excited, immediately told all of our close family... and then there was no heartbeat at my first US and baby measured behind. I eventually miscarried and my husband tried to be supportive but it was so foreign to him, he just kind of disconnected to give me space to heal.

Flash forward to last week, I nervously showed him a freshly positive pregnancy test. He was shocked because we hadn’t been even trying. His first response was something along the lines of “IF we keep it” and I told him of fucking course i wanted to after what happened earlier in the year.

It’s been almost a week since we found out and I don’t think he thinks it’s real. (My 6 pregnancy tests say different). My husband doesn’t seem to realize this time how my body is being affected by this pregnancy. I’m tired all the time, my nausea is bad, my sex drive is down. Every time my body is not “in sync” with his moods, he thinks it’s his fault and he’s doing something wrong and that I don’t want a physical relationship with him when in reality I just don’t feel well. It makes me anxious that if he’s getting this bent up over not having sex for one week - how will he handle postpartum?

He hasn’t shown hardly any excitement about this baby yet, a few small smiles when I mention something. Last pregnancy he was exuberant and always commenting on how i was carrying our baby and how amazing it was that we were gonna be parents.

Is he just trying to protect himself in case of another loss? Am I too eager?

Or is this a bunch of red flags? Is he distancing himself because of other reasons?

I’ve been having a lot of anxiety induced dreams from this and plan to have an adult conversation with him ASAP because I don’t need the stress of this on top of everything else.
