NIPT testing for baby #2 at only 8mpp?

Brandy

Hi friends!

I’ll be 8 months postpartum when I get NIPT testing done for baby #2. Baby #1 is male, and I’ve heard that Y chromosomes stay in the mother’s body for a while after birth. Does anyone know how long? I don’t want my results to say boy if it’s not a boy 🤦🏼‍♀️
