It's your baby mama, so u shld decide. Ask ur hubby too if he wants to know right away. Personally, my friends wanted to throw a gender reveal party for me too but I didn't see the need for tt. I'd rather keep it low key and it doesnt matter to me if it's a boy or a girl anw. So I actually opted to go NIPT and I was told my baby's gender on the phone at 11 weeks.
