It would most likely be fine. But, I've had them with all three of my kids, this time I will not have one. The reason is that with my last pregnancy, they found soft markers for downs syndrome and also some fluid around the kidney's. It caused alot of worry for nothing, we had to have another 30 weeks ultrasound to check the fluid around his kidney's and then a 2 week old ultrasound on his kidney's. I refused further testing as the fluid was decreasing and I had read that this was common in baby boys and resolved itself around 1-2years old. I felt like we were put through unnessasary tests and lots of worry for nothing. So personally, I will never do one again without a medical reason. However, my first two came out perfect, which was reassuring and it was fun to learn the gender and have things for the babies before they came.
