Patient's question:
I am 17 weeks pregnant according to my last menstrual period, but my cycle is usually irregular and often delayed by about five to seven days. I saw online that my baby at 17 weeks is about the same size as someone at 15 weeks. At 17 weeks and four days, I had a prenatal screening test, and the ratio for open spina bifida was 1 in 10. So, I want to ask how I should proceed. Does it have anything to do with the baby being smaller?Doctor's answer:
Hello, according to your description, an amniocentesis needs to be performed.Advice:
This ratio has nothing to do with the baby being small. An amniocentesis is necessary for a definitive diagnosis, otherwise the risk is too high.
