How do you use yoghurt, btw? Do you put it IN the cup, or spread some on the surface?
So anyway, the cup was in for about 9 hours, and I had no discomfort in the vaginal area. I noticed that my pelvic and abdominal muscles were slightly tense, and I was getting the weird feeling in my tummy that usually comes with Aunt Flo. Probably need to work out, heh.
Come morning, I took out the cup - less of a hassle than on my first dry run, but not as smooth as with KY. I think dry runs are a pretty good idea, just to get my insides used to the cup before Flo comes along and adds another ingredient to the mix!
