Due to unusual spotting 2 weeks after my menstrual I went to see my ob, giving her my symptoms and receiving a routine pap smear she prescribed metronidazol gel for 5 days one dose per night. After my first application I woke up the following morning with a heavy flow of blood light red in color going about my day when I went to the restroom the blood on the pad was dark but when I wiped it was light red again could this be the affects of the gel. My period is pretty regular so now I m a little confused I was told that the spotting between menstrauls could be normal but I ve never had spotting occur in between my cycles could it just be the gel throwing off my balances
