unusual discharge...

For the past week I've had discharge bad to where it soaks my underwear and making my thighs chaf. I haven't eaten anything different sex life has been the same birth control is the same I've always been active but I have been doing more, working out then usual and a lot of Yard work. I see my PD Monday but I was wanting to know is there anything that could help stop it or at least tone it down? It's driving me crazy
