vaginapagina | Diva cup- Smell issues! (Reply)

I've had my Diva cup for several months now and I love it. I wash it frequently when using it and boil it between cycles.

Here's a little neccessary background info before I ask my question:
I've been wearing the Diva cup for about three weeks straight, if not a little more. I month ago I finished my period as expected, and a couple days later I started bleeding again. It hasn't stopped since, and it's been a small amount of blood every day. I am on HBC, and am now having my "period" as I should be during the placebo week (The small amount of dark blood has changed to the usual menstrual blood I have during my period and I have cramps, etc.). I've been washing and emptying my Diva cup regularly with no problems until today.

Last night I took out my cup, emptied it, cleaned it, and put it back in. It was odorless at that time. This morning I took out the cup and was met with not only an usually large amount of bright red menstrual blood but an AWFUL smell. I cleaned out the cup with warm soapy water as usual but the smell did not go away. I boiled it for several minutes and rubbed it down with alcohol. It's sparkling clean and sanitized but it still has a very funky smell. My vulva and vagina smell fine- no smell, no nothing. No irritation or strange discharge.

So what in god's name would make the cup suddenly stink like this? I checked the manufacturer website and didn't find any answers. I realize I have been wearing it an awful long time. What stumps me is that it was fine last night but this morning it was putrid. It's much better now that I've cleaned it, but it still has a smell- it's hard to describe, sort of like when you drink from a water bottle, leave a little water in the bottom of the bottle for a long time and then open it- that faint bacterial smell.

Any suggestions? I'd hate to buy a new cup since I just bought this one. They're also supposed to be very bacteria resistant, but I dunno... help!
