I just used a Divacup for the first time two days ago. I had no problems inserting it and I didn't have even a spot of leakage. Taking it out, also very easy for me. However, I got very bad pressure like cramps, they went away almost instantly when I removed the cup. Could it be too big? Too long? I am 20, no kids, and I am sexually active if it really matters. I tried looking into other brands, but there are just SO MANY! Looked at Meluna, Lunette, Rubycup, and the Lilycup. Any preferences on those?
