Me and my husband just started actively ttc this week. We already have 2 beautiful boys that are 8 and 5, but I've also had 2 MC's because I'm RH negative. That's where my blood attacks my baby's blood, but the doc can give me a shot that puts a barrier between us so I won't regect the baby. The shot lasts 2 years but it's been 5yrs since I've had one and I'm afraid if I do conceive I won't be able to get the shot in time cause I've heard it happens faster if it's a girl, and since I have 2 boys I'm afraid my mc's where girls. Does anyone know anything about this that might be able to ease my mind?
