Hi I was told by the doctor I had a yeast infection, therefore was told to take canesten1 comfortab. I inserted the tablet on the 24th before bedtime. Yesterday on the 25th I experienced abdominal pain then by night I had light pink discharge with white bits (almost as if it is undissolved grains of the pill). The pink discharge continued until this morning and now has turned to only bright red blood with the white bits still present. I am not suppose to experience my period for another 10 days. Is this an allergic reaction? What cause this vaginal bleeding?
