I'm glad you asked this question and I'll be interested in others' experiences and responses as well. I don't have one to share, but it brings up some general thoughts/feelings and questions on prenatal testing that I was going to post, so I hope you don't mind my piggybacking onto your question . . .
I'm 37 years old, pregnant with my 2nd, and living in Costa Rica. Though I have whatever host of medical advances available to me, I'm birthing with a midwife who firmly believes that in the event of a healthy pregnancy and healthy mama, ultrasounds or any other prenatal testing (except for a prepregnancy blood panel and urinalysis) is unnecessary, so I'm opting not to have any first-trimester tests and won't have my first ultrasound until 20 weeks.
With my son 4 years ago, I had a subchorionic hemorrhage so my pregnancy was heavily monitored. I bled heavily for the first 5 months -- very scary -- and I had countless ultrasounds and blood tests to determine the viability of the fetus and -- you know what? -- in the end, it didn't make one bit of difference. In the meantime, I was misdiagnosed with a bicornate uterus, told several times that I was definitely miscarrying, and experienced a host of other unnecessary anxieties because of the monitoring that was supposed to be so reassuring and helpful.... Ultimately, there was nothing that could be done regardless; he was going to grow or go no matter what we did, and it was really just for me to trust and have faith in the process and my body's own will. Gratefully he thrived and was born naturally and with strong health. We did find out later that he was born with a VSD (a hole in his heart), which was corrected with open heart surgery at 9 months. But, in hindsight, even all of those ultrasounds and tests did nothing to identify his VSD in utero -- and if it did, it still wouldn't have made any difference in his health or the post-natal care he received.
It's for each of us mamas to ask ourselves what our motivations are for having the CVS or any other tests done (and this is what I'd like to hear from you all out there). What difference would the testing make for you and why is it important? Is it simply because it's the establishment's protocol, or do you have a legitimate concern that such testing would alleviate? Is it worth taking the chance and possibly undergoing false worry? For me, there are no genetic anomolies on either side of the family, and identifying the child I'm carrying as having downs would not affect my decision to carry it or change my preparation for welcoming it into our family. I trust that I'm taking good care of myself, eating right, being loving and gentle to myself (and therefore to my baby), and I trust that my body knows what it's doing. So, that's why I'm not having the CVS or amnio. But I look forward to hearing the perspectives of those who have or are going to.
Thanks for posting and for listening, mamas.
