Dryness

So recently my vagina has been dry with a slight odor, but it’s not over powering and disgusting.? I researched it and basically I’m lacking estrogen, I have pills meant for that so I took one. but I was wondering, is vaginal dryness a symptom of the depo shot ?

I’m supposed to go to my boyfriends tomorrow and I know somethings gonna happen, therefore what is a quick way to re-lubricate it ? thank you !
