So..last week at 17 weeks I had the Harmony genetic testing done. Results I was told would be back between 7-10 days. I received them today on day 6. Thankfully my little nugget is perfectly healthy. Anddddd the Y chromosome was detected indicating a boy!

My inquiry lies in that I fell pregnant 3 months PP. My son is 7 months old. I read that even after giving birth traces of your child’s dna is still in your blood. I wanted to know if maybe that Y chromosome they detected actually came from this pregnancy and not from my last pregnancy? I was really hoping for a girl. My anatomy scan is on 2/22, next week. I know genetic blood testing are pretty accurate. They told me it would be a 98% accuracy. But what if? Has anyone heard of such things happening where you get a result then it turns out different then what was expected?
