Hello everyone ?. My husband has a negative Rh factor and I have a positive one. During my first pregnancy, they didn't tell me about the Rh immunoglobulin shot, but I had regular blood tests for antibodies, and our daughter inherited my negative Rh factor. With my second pregnancy, there were no problems until then, and we got pregnant as planned. Now they say that if you find this injection, start it from week 28 to week 32. And then after delivery within 72 hours, you need to do it. Question: who has encountered such a situation and did you administer it?
