Usually I wear my cup for the first 3 days of my period. Coming down to night time on day 3 I’d remove it and switch to a liner. My flow is really really light so I figured that I’d use my cup a little longer than 12 hours. I guess it was around 15 and a half hours when I decided to remove it. I took it out and it smelt funny. Kind of like a tiny animal died. I knew that I left it in too long because the blood was thick and dark and it was a little smelly, kind of like an old pad. I guess the smell absorbed into the cup or something because now the cup smells like it. I rinsed it, I soaped it with the correct soap and it still smells. I’m gonna boil it later to see what happens. In case it doesn’t go away, what should I do?
