I used Monistat 1 because of a yeast infection I had. On the 27th was the 7 day mark after using it & all my symptoms resolved then on the 29th (which is around the time I should start it) I thought I started my period but it was only a little bit not a full period flow if that makes sense. Is it the Monistat causing the spotting or should I be worried it is something else?
