Has anyone tried these? I just placed one for the first time ever and am amazed at the ease of insertion, which makes me worry it was TOO easy. The goal here is a mess free sex experience, as I’m seeing my LDR tonight for the first time in weeks. I’m day three on my period, moderately heavy flow, and my experience with the cup is major leakage the first two days if I don’t change it within 3-4 hours. How do I know this disk is sealed properly? Anyone have issues with leaks? Really not wanting to wear a liner but I feel it’s too risky not to... any advice appreciated!
