megha a doplr cannot be taken at home try to understand it is a complete sonography machine and a photographer is required to perform the examination so if the doppler is advised you need to call your doctor and ask her if it is very mandatory or you can skip the doppler till week 32

Dear my doc has advised to keep a regular watch on fhs nd m on complt bed rest so its not possibl for me to visit clinic regularly

Doppler needs to be done at an usg center usually 3d is done
