My last period was on may 12 n it lasted a week. From the past 3 days i'm having cramps and this brownish vaginal discharge. It started light and now it's dark and it's very slimy like mucus. I have taken the medicine meprate 50 mg which was prescribed by my gynecologist for getting periods. She asked me to take it if I didn't get periods for a long time. I started taking it two weeks back. I have cramping, body pains, bloating and breast tenderness. Does this mean pregnancy or miscarriage?
