I'm 28ws pregnant with my third, previous two miscs. I'm receiving the rhogam shot next week. Will my baby be safe till then? What's the purpose?

You are Rh negative. The Rhogam shot helps prevent the fetus, who may be rh positive, from triggering a reaction in your body if/when small amounts of fetal blood enter your system.Your body could develop antibodies that would break down the babies blood & place him/her in danger.The shot blocks that. In the 3+ decades it has been used it has been quite effective at keeping babies healthy.
Yes. Rhogam is given tio rh neg mothers to protect an rh pos bby. If you are rh neg, you should have received Rhogam after your miscarriages.
