FWIW it wasn't much easier being pregnant when I didn't realize that I was trans (knew I ID'd as male but didn't know it had a name or a cure at the time). It was surreal, kind of like it wasn't really happening to me, wasn't really me, but at the same time it was. Probably because I didn't identify with mothers, or becoming a mom, or all the other stuff that pertains to pregnant women.
I did ask my son the other day (who has always been a clingy love bug) if he missed having a 'mom' and he said no, he had me, and he loved me. I love that kid! (Love both kids!)
