No.
When I was in my early 20s and going through my first attempt at transition this question entered my head frequently. I felt devastated that I would never be able to carry and give birth to a child, wondered if I would go insane and start walking around with a pram/baby carrier with a baby doll inside. Never thought about pretending to be preggers though, I was probably more interested in the end product than the gestation period.
These days, being in my late 40s, it doesn't bother me. Were I born genetically female I'd be past child bearing age anyway. I know a number of women in a similar age bracket who, for whatever reason, have chosen not to have children. Plus I've also seen what women who have chosen to have a child have had to go through, biologically and physically, I do envy them...but not that much!!
