I have a couple of married friends. Both trans guys. They tried to adopt, and their options for surrogacy all fell through. So one of them carried their daughter. He didn't want to do it, but they were out of other options, so he did.
He wasn't "female whilst pregnant". He wasn't a mum, a mum to be, a pregnant woman, or any other term like that. He was a pregnant man, or when needed for clarity, a pregnant transgender man.
I'd ban you too, in a heartbeat, if you brought any of that bullshit in to a trans or queer sub that I moderate.
You having a trans kid doesn't give you permission to walk all over the voices and experiences of trans people trying to navigate pregnancy
