Negative blood type and Rhogam

Hi all!

I recently found out my blood type is O negative.

My obgyn said I should get a Rhogam injection at 28 weeks and then 72 hours after giving birth.

I’m a little nervous about this injection especially while I’m pregnant.

I’m thinking about opting out of the shot at 28 weeks and waiting to see what the baby’s blood type is at birth.

If baby has a negative blood type then the shot is not needed at that time.

Thoughts?
