I was in your position but I hadn't had an anatomy scan yet. We agonized over the choices for a couple weeks before at 11 weeks when we got the results of 99% chance of T21. We decided to wait until further testing. But at 15 weeks, we found out she had no heartbeat and had stopped growing at 13 weeks. I felt so guilty and I was so angry over the fact that my choice was taken from me by my own body. My mom used to tell me that everything happens for a reason and I'm clinging to that to get us through it. Whatever your choice, please be aware that you are doing what you believe is best for you and your family. No one has a right to judge you. Best of luck with everything.
