There are currently two ways you can receive RAADP (anti-D immunoglobulin):
a one-dose treatment: where you receive an injection of immunoglobulin at some point during weeks 28 to 30 of your pregnancy
or a two-dose treatment: where you receive two injections; one during the 28th week and the other during the 34th week of your pregnancy
tan color is ok
if you have another episode of bleeding, you have the option for another injection if you need it with antiD immunoglobulin.
you most be Rh negative and there is a chance your baby is Rh positive
it sounds like your doctors are aware of this and taking care of it
let me know if you have other questions.
