I just bought a Diva cup (size 2). Day 1 of my period was great. Yesterday was day 2 and it was a complete nightmare. The cup kept sliding out & leaking. I tried pushing it in, as well as taking it out, washing it and reinserting it no less than 10 times during the day. At one point, when I went to go to the bathroom, it actually fell out! It even leaked last night. I have very, very heavy flow on days 2 & 3 of my period. For example, this morning I was woken up by the leaking at 5:55, washed everything and when I re-woke up at 6:30, the cup had 1/4 oz of blood in it. It wasn't feeling one bit comfortable this morning at 7:30, so I re-did it again, and it had another 1/4 oz. When I put it in at 6:30 this morning, the uncomfortableness was due to the stem pinching my labia, and also the bottom part of the cup outside of my vagina. My cervix is low during my period, I think - I can feel it when my finger is only half way in my vagina. Right now, it seems a little uncomfortable, but it's hard to tell if it's from the cup or just because of all the fiddling around all day yesterday. I do not know if I need another brand of cup. I was looking through all the pages on this community to figure it out, but think that personal advice would be better. If it matters, I've had 3 children and am in my 40s. Another problem I'm having is that I was hoping to have my 12 yr old daughter try one. She does ballet 6 days a week & just got her period last month. I had been doing a little research about dancers & their periods and had found the Diva Cup. I didn't even realize that there were other brands :-( If I'm having all these issues with Diva, I do not know if the Diva cup size 1 would work for her, but really have no clue. Any advice on that?
