AFP results

Sara • IVF pregnancy Mama to baby girl 11/2/19

I had my alpha fetoprotein checked last week at 16 weeks... This week I got the results and it's slightly elevated at 2.06. I won't get any results until my level II ultrasound in two weeks!! I've heard there's lots of false positives, but so worried that my girl has neural tube defects! Has anyone else been in this situation?
