Im O negative and had to get the RhoGam shot. Point of this post is to ask how many mommas are Rh negative and have had multiple pregnancies, and how many babies? I want a big family of 4-5 kids, and plan on conceiving my next baby in a couple of months, but I’m worried that my blood type will Interfere. My baby was born with o negative and i didn’t need the shot at the hospital, but my husband is A+ and one of my babies will have the chance of coming out with positive blood type. So Rh negative mommas, please comment how many babies y’all have had.
