Can any1 tell me the exact fetal age or how many weeks am into? Tiffa (sep9, 2019) shows 20 weeks 6days and Doppler (Dec 7, 2019) shows 36weeks 2days. But according to LMP baby chakra shows 33 weeks. Which is correct? Am worried please doctor respond urgently.. I have attached pics of Tiffa and Doppler.
