A Rhesus negative blood?

Rhesus positive (Rh+) blood cells have antigens (markers). When RH+ blood is mixed with rhesus negative (Rh-) blood, the Rh- cells make antibodies to destroy the Rh+cells.

The majority of people are Rh+, so it is likely your partner will be and this can lead to your baby being Rh+.

It is unusual for the babys blood to get into your system, but if it did your body would take around 3 days to start making antibodies. These can cross the placenta and make the baby anaemic.

To stop this from happening you would be given 2 injections of anti D, one at 28 weeks, then again at 34 weeks. This is a tempory antibody that will get rid of any of the babys blood in your system and stop your own immune system from making their own permanant antibodies. You would be given an extra injection if you have a bleed in pregnancy or a hard fall that could potentially cause a bleed. After delivery they test the babys blood from the cord - if the baby is Rh+ you need one more injection.

I have rh negative blood but my daughters have positive. All that happens is you get a couple of injections. The issue would be with the second baby so they give you injections to stop you forming anti-bodies that would attack the second baby. I don't remember getting any injections the second time I was pregnant.

I am the same i have had two healthy baby's, with no complications whilst i was pregnant, i just had to have a couple of injections in the beginning but nothing major.

i have Rh- blood too and it does cause some concerns during pregnancy , i had to have shots to make my blood cohabit with my babies during term . my babies were positive blood and i actually could have harm them . don,t be alarmed , there are so much that has happened medically since i was pregnant . just eat right , lots of exercise , feed your cravings and stay calm .

As far as i was told it isn't a huge issue, they just give you a shot to immunise you if your baby's blood type is different than yours, as there could be a risk of complications for yourself more than for the baby.
