vaginapagina | Smelly down there (Reply)

Over the past few weeks i've noticed that my down there parts have smelled... different.
I wouldn't say it's yeasty (though i honestly dont think i know what yeast smells like) and there is no itch or burning when i pee.
I have also noticed that i've become less lubricated during sex with my boyfriend. We don't use condoms as i am on the pill (mononessa, a monophasic pill). I used to be on ortho tri cyclen lo, and think that this new pill may have lowered my sex drive (although i've been on it for 3 months and haven't noticed anything until about this past month) Also, sometimes when we're having sex the inside of my vagina feels sore and irritated, im assuming this is just from being not well lubricated. I would rather not refer to using lube with sex, and i used to be able to get very wet very easily. Is the monophasic pill causing this?

Also sometimes when i'm just standing around i will feel a dull pain like the coming of a UTI, but i have no other UTI symptoms.

What could this be? The smell could possibly be considered a fishy smell, but i really don't know. Are there any soaps I can use to clear this up? Or is it a possible std of some sort? We've been monogomous for months now, so it's not like I could have contracted something. And if i did from him, wouldn't symptoms have shown earlier?

All opinions/advice are appreciated. You girls are great!
