No discharge

Over the past few months I haven’t had much discharge lately. My sex drive has went completely down and im still ttc. I take probiotics to keep my vagina healthy but the dryness is becoming a problem. It doesn’t hurt to have sex but im getting concerned that even when im ovulating nothing is there. I just turned 32 my gyn said my progesterone is normal and I drink water so what’s wrong with me?? I haven’t been to the gyn since last year just for reference. I have conceive plus lub but don’t get a chance to use it.
