I was Rh neg & had a bone marrow transplant and became Rh pos. I had to do IVF to conceive & learned I was anti D pos before my embryo transfer. I was sent to a perinatologist to discuss complications. I am a nurse & had no clue what to expect.

I was told that the Rh issue doesn't become a problem until the 2nd trimester. I m/c at 10 weeks. If the preg would have proceeded I would have had frequent u/s, blood titers drawn every 2 weeks, and an amniocentesis. If with these tests it indicated that the baby was anemic it would require intrauterine blood transfusions (thru the umbilical cord). These have complications & the benefit must outweigh the risk. If you are far enough along that the baby could survive they would rather deliver and then give blood to the baby after.

The perinatologist was very reassuring that I could have a safe preg with proper monitoring (my m/c they assure me was not due to my Rh issue). You should be watched closely be a high risk OB or a perinatologist. I would ask to see one before you get preg again just to ease your mind. I am here if you ever want to talk about this further or anything else for that matter. Take care & God Bless.

i am rh neg and my first preg went to term. they have to give you the shot but if i remember right i was in 2nd tri when i got it.
you only have to get it if one parent is neg and one parent is pos. if both are neg i dont think you have to get it. you might due to two negs make pos.
did you get another shot when you went into labor with first???? you should have.

hi thanks for both of your advice.
in response to the latter i was given anti d injections throughout my pregnancy and when i gave birth but this didnt stop me developing the anti bodies. apparently in a very small percentage despite being given the anti d shots you can still develop the antibodies.
our health system is so shit its impossible to understand half the time!

If you are rhesus sensitised & you have the anti-D in your system, please consider donating your blood as the antibodies may help other pregnant women who are rhesus negative.

In regards to the previous post, if a woman is anti-D positive, pregnant women or anyone for that matter would not want to recieve blood with it, even if they are anti-D positive themselves. The goal is to keep the titer level in your blood as low as possible. This is especially important if they are still within the child bearing years. When a women is positive for anti-D and either delivers or miscarries a child she still should receive the Rhogam injection in the hopes of preventing the development of further anti-antibodies and a higher titer level. A woman that is anti-D positve, as any person WITHOUT the D- antibody can receive blood products that do not have the D antibody (don't confuse anti-D antibody and D antibody they are 2 different things). People with the D, C, and K antibodies are encouraged to donate blood (different then the anti-D, C, K antiibodies).

I'm also Rh-negative. I received several Rhogam shots during my first pregnancy (my son is now 2). I was given the first shot at only 6 weeks because I had some bleeding, and my doctor wanted to make sure I didn't produce antibodies. Later shots were given at 22 weeks and right after birth.

When a missed miscarriage was diagnosed with my second pregnancy in Aug., I was immediately given another Rhogam, before even my D&C. Blood was also taken after the miscarriage to verify that I hadn't produced antibodies.

In follow-up discussions with my doctor and nurse, I learned that I have to monitor my cycles closely to watch for another early miscarriage. If I should miscarry as early as 5-6 weeks not knowing I was pregnant, I could produce antibodies simply because I wouldn't get a shot if I didn't know I needed it. Boy, this is confusing, isn't it???

Now, we're trying again and I am monitoring my cycles watching for possible pregancy etc. Also, frequent contact with my healthcare providers has helped me make the best of the situation.

Anyway, even though I'm not an expert, I do recommend finding a good high-risk specialist, working closely with that doctor, and keep asking questions until you do understand.

I wish all of you Rh neg girls the best with your situations. We certainly have extra challlenges. Don't give up! Take care. I will be thinking of you.

im rh neg i miscarried at 12 weeks i wasnt given any injections and no1 even explained to me the problems that i could have because of my blood group :-(
