I have a mooncup, and I recently sized up to the postnatal one due to leaking. Leaking is still a huge problem, and it seems to be due to overflowing. About three times today I've had leaking and now I'm a bit concerned. I'm emptying it regularly, it's day 3 of my period and there's a heck of a lot of bright red loss. It's making me really sad, because I don't want to have to go back to tampons. Is there a solution? I was n the pill for 17 years prior to having Esme, so I just don't know what 'normal' is and as I'm still breastfeeding there's no much that can be done to fix it, I don't think.
