Hey Everyone. I have been using my DivaCup size 1 for about three months now. But just have started to notice a bad smell the past couple of days after I have finally perfected my seal so no more leaks! But The smell is making me wonder.... I wash it after I take it out every time. If I cant use antibacterial soap and warm/hot water I just use warm water( like in a public bathroom). But today I left it in for a long time. Mostly because I wanted to know just how long it would hold on a heavy month, like this one. After the entire day (I emptied it this morning around 11 and then a while ago at around 12:15 am.) it wasn't full, but has this bad smell. I washed it twice. Still smells. Is this because of leaving it in too long? And its not just any blood that stinks, it's the cup. It was a bit stinky yesterday, but I thought nothing of it. But today It still stinks. I have washed it with soap and water every time I removed it. Which has been about 5 or 6 times the past two days except once, when I was out with my mom at a restaurant. I just had her give me a water cup and paper towels then as I normally would out in public. That is when I noticed the smell. I boil it before and after every cycle use. Should I try a vinegar bath or something? Please help. I LOVE my cup and would HATE to have to throw it away after three months. I wont go back to pads, PLEASE HELP!
