Question 2

just got home from doctor. she said i have rh isoimmunization. looked it up online and now more confused that ever. can you explain what it means to have it?

Accepted Answer

Pregnancy concerns: The rh factor is found on the red blood cells of 85% of people in america, they are rh positive.  You would be rh negative, because you do not have the rh factor on your red blood cells and because of that you have developed an antibody against the rh factor.  That antibody protects you but can cross the placenta when you are pregnant and can cause severe problems for your unborn baby.

Question 10

can i have a vbac if i'm rh-?

Accepted Answer

Of course: Rh status has nothing to do with the choice of VBAC delivery. It has everything to do with the type of uterine incision you had initially, the number of C-section deliveries you’ve had so far, and the OB ‘s opinion of your degree of risk for uterine rupture if you do decide to have a VBAC ... 
Best advice is to discuss with a Maternal-Fetal OB specialist about your risks before any decisions made
