I am 33 years old, pregnant in week 13, two weeks ago I did the rubella igg and igm tests, I got a negative igg result and the igm was positive, but they asked me te repeat the test.i did and still waiting for the results. We did an ultrasound for the baby today and everything is normal, the heart , the brain and the development of the baby also. I am very worried, what shall I expect?
