I started my period 2 days ago and everything was normal. I've been using the mooncup for a couple of months now and haven't had any trouble with it. But this morning when I took it out it smelled really weird. Last night it was fine, but this morning it smelled rotten. I rinsed it really well and washed it with soap, but it still has a slightly odd smell. I haven't yet had a chance to boil it, maybe that would help. I haven't had it in all day and my flow doesn't smell weird anymore. Does anyone know what might have caused this? Or if my mooncup is still safe to use?
