Is there anything I can eat or take to help put me "in the mood" that won't interfere with conception?

I don't have much of a drive lately and we want to have another baby. Goodness how I wish there was a little blue pill for women, but there just isn't! I've looked! Does anyone know of anything that I can safely take, supplements, food, etc. that won't interfere with my hormones too bad to inhibit conception? Foods to put me in the mood? Supplements? Any feedback or advice would be nice. Thanks so much!
