I did something rather silly today.
I put my diaphragm in late this morning for its usual use and subsequently forgot about it for several hours, as I usually do--even if the condom was sound and intact, color me paranoid. I figure it doesn't hurt, so long as I take it out before too long, and it might offer a little extra protection.
Well, it usually doesn't hurt, but later this afternoon I decided to go for a dip in the pool. It's summer and Florida, mid 90s Fahrenheit and humid, and I go swimming almost every day. The long and short is, I didn't think to take my diaphragm out beforehand. D'oh!
When I took it out this evening, a little pool of warm, chlorinated water trickled out with it, much to my dismay. While I'm grateful that the chlorine makes it fairly unlikely I've picked up random vicious bacteria, it seems it's probably also killed off my friendly acidophilus. Tomorrow morning I'm going to get some yogurt and attempt to stave off a yeast infection that seems to be developing already.
On the up side, I'll probably never do it again!
Anyway, for the few of you diaphragm users out there, something to think about. I don't have any official information about the advisability of having them in in a swimming pool, just my own experience and deduction.
