So I think I am going to try a vinegar douche. I am just not sure when to do it. We will Be frequent BD from AF to 2-3'day cut off. probably every other day. So should I use one before every BD, just the first time, or just the last time? Any suggestions? I also have replens and refresh and I'm leaning towards refresh since it works for 3 days. Thanks for any help you can give.
