I started using my Divacup about five months ago and I just love the freakin thing. After a couple of cycles and a couple of posts regaring where the cup is supposed to sit, I have had no problems at all. However, my period seems to have changed some. I am almost 37 years old and my period has always been regular and on a 28-day cycle. Now it seems to have shortened a day or two. Besides that my cramps have become almost non-existent. DONT GET ME WRONG--THIS IS GREAT--but I am having trouble predicting when I am going to start now. With my cycle not landing on day 28 and no tell-tale cramps to send up a red flag, (no pun intended) I seem to be getting caught off guard. I have read about many cup users who report lessening of cramps and somewhat of a change to the number of days in their cycle, but does it stay that way? What are other's experience of this?
