Rubella test

B

So I had my bloods done in May when I was pregnant but sadly miscarried. My rubella came back as IGG, positive and gave a figure (can't remember what).

I fell pregnant again in June - I'm now 8 weeks and I had my bloods done Wednesday again as there was suspicion of rubella in my office, but that turned out to be false, and it has come back as IGM.

Dr said we need to amplify the blood (I think) to do a second test and depending on that result we need to do all sorts of tests to see if the baby has CRS. Or if we need to terminate.

Help a mama out here. Has anyone had this? And have their babies been fine? Or if your baba had CRS, what did you do?
