Rh negative blood type mommas read

I found out I’m rh negative and I need to get a shot to kill off or prevent antibodies. If any of you are this blood type and we’re or are pregnant you will know what I mean. If you are this blood type and had a baby and the shot can you talk me through what is happening. I’m so so so worried about my baby, I read up about my blood type and scared myself. I’m 23 weeks and I’m getting the shot February 20th but is my baby ok until then?
