Panoramic Testing

I got it done once in December and results came back “inconclusive” because there wasn’t enough DNA in it, so I got it redone two weeks ago and they said the same thing. I had to get blood drawn twice and I’m frustrated because honestly I don’t believe that, I had the same nurse for both, and the first time she didn’t even get blood out of my vain she missed that spot. I’m frustrated because I didn’t want to wait on my gender, but of course now I have to wait. They said it doesn’t mean anything is wrong with me or the baby, it happens occasionally. But it seems like everything is happening to me lately and I feel overwhelmed.
