@MapleCreekBride:  I’m also RH- and had an early miscarriage earlier this year.  I was also worried, as I had read about needing the RhoGam shot, but my doctor said the fetal development was too early to have blood interaction.  They did give me the shot since I asked for it, but from what I understand, it wasn’t necessary.  Unless you were a lot further along, I’m guessing your doc also determined it wasn’t necessary. 

With my current pregnancy, I will have to get Rhogam at one of my upcoming appointments since DH doesn’t know his blood type.

@MapleCreekBride:  at the time of your m/c the doctor should have given you the WinRho/Rhogam. It is a bit odd that he did not. However, with your next pregnancy, they will give you the shot at 28 weeks. There should be no risk of blood exchange between baby and mom prior to 28 weeks, since none of babies blood (which could possibly be Rh pos)  should be exposed to mom’s body and therefor should not trigger an immune response by mom (and when I say immune response…  That would only occur If you had indeed developed an Anti-D from your previous pregnancy).

If during your next pregnancy you begin spotting prior to getting your shot at 28 weeks, go to your doctor or ER and they will give you a smaller dose of WinRho just in case there is a blood exchange.  

Lastly,  you will have prenatal blood work drawn when you first become pregnant and if you have developed an Anti-D from your first pregnancy (which is still quite a rare occurence),  they will continously monitor that antibody level (called a titre) to ensure that it is not rising and subsequently affecting baby. And even in the worst case scenario, they have treatment options to keep baby and you safe. 

I hope that made sense. PM me if you want me to clarify anything. 


P.S…  Also also a SK gal here!  🙂

@MapleCreekBride:  I remember getting the shot around like week 25 or so with my first pregnancy. I’m O- blood type and one of my twins was A+, one was A-. This wasn’t anything that was discussed early on in the pregnancy and from what I understand, it wouldn’t cause a miscarriage. The problems involved are with the baby in terms of jaundice or anemia. 

My case is probably a little stranger than most since I had twins, one Rh+ and one Rh-and everything is just fine. They’re 5 1/2 now and perfectly healthy. 

I know how things get stressful when TTC and pregnant! But.. good luck!

I had pretty bad spotting at the beginning of my pregnancy (it was “threatened”), and the doctor had me immediately tested to see if I was Rh-. She said I needed the shot right away if I was. It turned out I’m not, and the spotting ended and I’m very much pregnant. This is my first pregnancy. 

If I were you, I’d just be sure to communicate with my doctor as soon as I got a BFP and let her know you’re Rh- and have had a miscarriage. I’m sure she’ll know what to do.
