Hi. I'm 52, No Children. Periods Regular To The Day.

Hi. I'm 52, no children. Periods regular to the day. In the last year I've experienced large sudden clear watery discharge during period. There is no warning and goes everywhere. Through tampon, pads and clothing. I have missed work because of it. I also feel I lose clear fluid during hard work, like yard work when not on period. I have to change clothes several times. I'm normal weight, healthy and active. Please help! How can this be stopped so I can live life without a depend on!
