Hello, I can understand your concern about your pregnancy, as you were already aborted once. First of all, i would like to tell you that any kind of vaginal discharge during pregnancy is abnormal, either blood, white or brown...According to your history, you have brown discharge for one long month and its abnormal, but your doctor prescribed you the right medicines in form of HCG injections and duphastone tablets. Both these drugs will help to maintain pregnancy in such cases, so never skip the tablets or injections. Chances of abortion is more during 1st 3 months, so you will have to take injections and tablets for 1st 3 months. You also need to take few precautions also, like don t have sex, take proper rest, have a proper diet with folic acid tablets also, don t carry heavy weight, etc. So all and all, you will have to take these medications and take enough precautions, specially during 1st 3 months. Be relaxed and don t take tension.....
