Had molar pregnancy, i have done d and c 45days before. i am getting white color discharge every day. is it common in this case?

Call your GYN MD: You need to call your GYN MD who performed the D & C post molar pregnancy to have a beta hCG blood test done to monitor the resolution of the pregnancy. Moreover, he/she can also determine the significance of the white discharge after evaluation. If all the molar tissue was not removed at the D & C, the blood test will make that determination.
