Hello, I would be happy to help you with your question.
I am terribly sorry about your losses. Congratulations on your current pregnancy. The increased NT indicates a genetic problem with the baby - most often an extra or missing chromosome. The addition of extra folic acid
suggests that they were worried about the possibility of spina bifida
. The extra folic acid is certainly harmless. Here is what I would recommend:
1. Continue the extra folic acid - as much as 4mg per day is totally safe
2. Ask for an ultrasound
for dating of the pregnancy at 7-8 weeks
3. Ask for "first trimester screening" which can be done at about 11-12 weeks and involves a blood test
and additional ultrasound
4. If she miscarries or needs a D&C, then ask for a karyotype
(chromosome analysis) of this pregnancy.
