[|Human|] my sister in law underwent IVF . she had normal B ChatDoctor level THE ivF WAS DONE ON 1ST jUNE, 17 TH JUNE BChatDoctor LEVEL Was 206 and then on 22nd it was 600. Dr. asked for USG on 9th july for visualising cardiac activity. but she told that still the cardiac activity has not appeared and also size is 7 weeks 5 days. what could be possibility
[|AI|]  Hi, according to IVF timing the gestational age should be around 6 weeks, but it is more on scan, so the possibilities of twins or abnormal pregnancies like molar pregnancy are there but as Chat Doctor levels are within normal range there is possibility for multiple gestation like twins. By this time cardiac activity should be noticed, but it is not appeared yet. So you can repeat the scan in the next week to rule out above possibilities, transvaginal scan will detect heart beat earlier than transabdominal scan. Take care.
