I just started my period this week (first one in 16 months!!!) and am using my mooncup from pre pg... it seems fine to use, is there any reason I need to change to the other size if it isn't leaking and feels fine?
It took me some time - and I am still veeeery careful! I hated using pads, missed my lovely mooncup (even though everyone in my family thinks it's gross and husband retches when i talk about it!)
