I used the Sckoon cup my last menstural cycle. Love the concept but I couldn't get the thing to stay in. It felt like I had a good seal and then I would stand up and it would eventually gravitate down. The only way I can describe it is it was like I was giving birth to my menstrual cup and it was crowning. I know not the best way to describe it but that's what it was. I really want it to work but I am at a loss. I have had 4 vaginal births so I'm not sure if that plays a part. Advice would be great and I've searched a ton of journals and couldn't solve the issue.
