His and Her Health

My boyfriend and I have been noticing my steadily decline in sex for the past 6 months now. It's finally gotten to the point where I am just not turned on anymore, and don't really have much of a physical or emotional desire to have sex. Things he'd do that used to drive me crazy just don't phase me, I have no response to it anymore. It's frustrating us both and making me feel kind of depressed. I want to be turned on and have fun having sex, but the arousal just isn't there anymore.
We've been speculating on why. Within the last year I changed my birth control from Lo/Ovral((because I was having really bad mood swings)), to Zovia 1/35e. I also upped my dose of Trazodone((for sleeping)) from 100mg to 150mg to offset my unbalanced mood swings around the same time.
It didn't get really bad until I had a yeast infection and use the Monistat 3-day cream. Whenever I would use the cream, it would burn me down there really badly, and felt as if someone was poking needles into my vagina. After that treatment, it hurt to much to have sex, so I asked him if we could lay off sex for awhile because it hurt too much. Ever since then my libido is nonexistent.
He's frustrated because I'm not having fun when we have sex, and I just feel like something's wrong with me... We've considered just stopping the birth control all together, but I'm on my second week and not sure if that's safe/healthy.

Sorry for the lengthy thread, I just really would like some help with this.

Katzchen, please check with your GYN about using a different medicine for a yeast infection. Also ask about the side affects of the other medicines you are on.Be sure you bring up the lack of desire and low libido to your doctor.
