Soft Cups issue

So I tried a soft cup for the first time yesterday and it was all good for the first hour then I had extreme cramping that felt like contractions I was doubled over and crying in pain and not to be TMI but my body pushed out the soft disc into my underwear! After it was out the cramping slowly eased up. Has anyone ever had this happen? I want to try other period products because I overflow tampons and pads cause chafing but after that experience I am super nervous to try anything else! Help anyone else had things like this happen???
