I got my NT scan done today (attached reports). Doctor said everything seems fine but the blood flow to fetus is less. She suggested aspirin 150mg daily and some other iron, calcium supplements. She also assured that there is no complication, but advised me to eat healthy. I want to understand what causes this issue (decreased diastolic flow / placental insufficiency). And what care to be taken to get this condition under control. I don't have any health issues. No diabetes, thyroid, etc. But BP was li'l high today for the first time (140/90).
