I am 42 and have a pretty regular menstrual cycle. For almost a year now I have had a problem with flooding a clear colored liquid during my period. I wear tampons and mini thins and I will think I'm flooding but when I go to the bathroom my pad is soaking wet but not with blood. It is a clear liquid that smells like straight amonia. I only have the discarge and smell during menstruation. What could be causing this?
