I had those test done for all 4 of my pregnancies. My husbands 1st son had a birth defect that was not detected because they did not do those test. His delivery became troublesome because he needed to be transported immediately to Childrens Hospital for care. Had the test been done he could have been delivered in a saver situation. He is fine now married and expecting his first child any day. That is why we had the test. Our 3rd daughter had a terminal birth defect, she was born @ 7 months and was with us for 7 minutes and returned to the angels. We found out at 18 weeks that we would not be able to keep her with us for long. We decided to keep her with us as long as we could.
We had tremendous doctors and one would always ask prior to any test we took, "what are you going to do with the information" I guess he meant will the results of the test change your mind as to wether or not you will continue with the pregnancy. If it is not going to change your plans (if you will keep the baby no matter what the results) why do dangerous test.
with our 4th child he was high risk we did the initial blood test and some advanced ultra sounds but choose not to do anything more invasive. That was based on our results from the other test. It did not matter to us what might be wrong with him and none of the test were needed for a safe delivery.
What the dr office did do as common practice with anyone who was high risk had to come in 2x a week after 32 weeks for a non stress test and ultra sound. I thought that was a waste of time until the second visit the first week and there was a problem. I came back the next day @ 3:00 pm and delivered by emergency ____@____.com i had not gone in for those test that I thought were a waste of time my son probably would have been a case of fetal demize. He was moving around up to the minutes before he was delivered.
I think if you have a good dr you can talk all this over with him or her. The test can be very helpful especially if special precautions need to be taken at delivery. But you also need to ask your self what are you going to do with the information. We had a very rare birth defect that affected our 3rd daughter. We did talk to a genetics specialist so we could pass on information to our other children when the time comes for them to be parents.
Ask yourself what you would/will do with the infornation you get then you can decide if you want to take the risk of the more serious test.
God bless and take care of yourself and your new little one. I hope everything works out.
