Normally, till 28 weeks ultrasounds are done in gap of 4 weeks, after 30weeks it's 2weeks gap.<br> But than it depends on case to case.Higher risk pregnancies <u>need</u> close monitoring. <br> One need to discuss with her Gynae about it, considering cervical length and funneling too.

ur gyno will guide when the next one is needed. in both of my pregnanies, i got 5 ultra sounds done

thanks to all

Hi Vasudha frequency of&nbsp; the Ultrasound depends on the case as the rays arent good for the baby normaly if the pregnancy is smooth its done on every trimester&nbsp; your next will be due within 2 to 3 weeks I think your doctor will tell you exactly when it's needed to be done.

hi vasudha, every gynaec does ultrasound twice, your next will be done soon. your gynaec will inform you. till then take rest and relax. happy pregnancy !!
