What happens if I don't get a rhogam shot after miscarriage?

RhoGAM: If your blood type is negative, and don't receive the rhogam, you may reject the next fetus, if you become pregnant with a blood type positive baby (if your partner is blood type positive).

Unlikely: This is an unlikely cause. However, there are blood tests the doc can run on you to see if you have been sensitized in any way to the rh factor due to that earlier event. It is a test that is often performed early in pregnancy, so it may have been part of your 2nd pregnancy workup but never discussed (if it was negative).

I recieved rhogam shot after a miscarriage at 5 wks last tues because I am o-. Not ready to try and conceive. How soon can start birth control pills?

Need a neg preg test: I'm sorry you miscarried. You may start birth control as soon as you have a negative pregnancy test. that may be as soon as 2 weeks after a miscarriage. Ask your doctor for a blood test or a urine test.

I had a rhogam shot when I found out I was pregnant I miscarried, do I need another rhogam?

I had a rhogam shot when I found out I was pregnant I miscarried, do I need another rhogam?

Yes: You need another shot as you may have been exposed to significant blood from your baby and if that baby was rh+ you have a risk of developing rh antibodies.

Had 2 miscarriages since my last rhogam shot think I may be preg again do I need the shot or is it too late?

Had 2 miscarriages since my last rhogam shot think I may be preg again do I need the shot or is it too late?

Probably not: You should be evaluated for the need for Rhogam anytime you bleed during a pregnancy. At this time, you need to have a test for Rh antibodies that is standard with your first OB labs. If it is negative, you would only need Rhogam in early pregnancy if you bleed. You would then get a Rhogam shot at about 28 weeks routinely. See your OB.

Will getting the rhogam shot help with the next pregnancy if I've previously had two miscarriages?

Will getting the rhogam shot help with the next pregnancy if I've previously had two miscarriages?

Rhogam: If you are Rh Negative, then rhogam is indicated by 2nd trimester to decrease the risk of inducing red blood cells break down (hemolysis) in the fetus. Close follow up with maternal fetal medicine (high risk pregnancy) specialist will be needed.

Miscarriage in Jan. Now 6 months. Got the rhogam shot when I miscarried. Dr. said I will get 1 at 28w, birth. Is that fine or should've had 1 earlier?

That's fine: Your doctor is right, you would get one earlier if any other problem like bleeding or so, but otherwise with stable pregnancy that would be the routine, wish you a healthy pregnancy and a healthy baby

When is the latest I can get rhogam shot? I received one when I miscarried does that protect this baby too?

No it doesn't: Rhogam should be given to Rh negative ladies within 72 hours of any obstetric complication or fetomaternal hemorrhage risk, e.g. abortion, miscarriage, ectopic pregnancy, CVS, amniocentesis. Prophylactic at 28 weeks pregnancy, and within 72 hours of delivery. One shot doesn't provide long lasting immunity, this is kind of passive not active immunization, as there is no microbe to immunize against

If I suffered a miscarriage without a rhogam shot, what happens if I get pregnant again?

If I suffered a miscarriage without a rhogam shot, what happens if I get pregnant again?

Rhogam: If you are rh positive there is no problem and Rhogam is not indicated. If you are rh negative there is a potential chance that you will get sensitized depending on whether you get transfused a certain amount of blood from a rh positive miscarriage.

I am rh- and after my miscarriage I did not recieve the rhogam shot, will I ever be able to carry a baby to term?

I am rh- and after my miscarriage I did not recieve the rhogam shot, will I ever be able to carry a baby to term?

Get tested: Only a small percentage of rh negative women will develop antibodies to the rh protein after a miscarriage. Ask your doctor or midwife to test you with an antibody screen to see if you have any antibodies. Even if you did develop antibodies the chances would be very good that your next pregnancy would be relatively normal.

I'm rh-. Had miscarriage on Sat. Lots of bleeding. Took preg test it was negative. I took rhogam shot Monday. Not sure if past 72 hr mark. Too late?

Unclear: It is not clear what is going here. If you took a pregnancy test right after a miscarriage then the test would still be positive to some degree. The doctor treating your miscarriage can clarify what happened and clear up the timing of the Rhogam shot.

Rh- I Had a Miscarriage I got the rhogam shot then now I am 28w I haven't received it yet for this pregnancy Is it safe to get it after 28w? Scared

Strict time line: There is a strict time line for the administration of rhogam. If it is not given at 28 weeks, the potential beneficial effect may be diminished or there may be no benefit at all.

I had miscarriage a year ago and never received a rhogam shot. I have A- blood and hubby is A+. Will I be able to conceive again or do I need the shot?

I had miscarriage a year ago and never received a rhogam shot. I have A- blood and hubby is A+. Will I be able to conceive again or do I need the shot?

OK to conceive again: If you were to have any problems after the miscarriage it would have already happened. When you get pregnant it will be necessary to receive the injection during the pregnancy and or after delivery to protect you from a blood reaction. You will be fine. The Rhogam is to protect you from the babies blood should you be exposed during delivery. Good luck with your new family.

Had miscarriage at 6w3d. On 4/2/13. Have a neg. Blood. Er/urgent care docs did not give rhogam shot. Is it needed? Not sure of hubby's Rh factor.

You need it soon: 85% of people have rh+ blood, so playing the laws of averages, there is a very strong likelihood that the father was rh+. There is always the chance that the baby would have been rh- and Rhogam wouldn't be necessary, but why take the chance. It's to prevent a problem with future pregnancies.
