Much to my "Shagrin", We can not ever no what a GG go through.
We can have a baby we do have cramps or pms. However I am told that some TS's do have a form of PMS sometimes, Hormone! But the thrill of wearing great clothes and getting away with alot is woinderful.
I thought several years back a technique was developed where a man could carry an embryo in the abdominal cavity far enough for the baby survive. As far as I know it just hasn't been used yet.
