My vag dried up..help!

Im 26 and have 3 children from a previous marriage. I began nuvaring in February of this year and just this month I've recently hit a dry spell...

I'm wondering if it's my birth control, from that douche after my period that i very rarely do, stress, or if I'm getting old. I've never had this problem...normally it's too lubricated. I can't even enjoy sex because it hurts to much.

Help! Tips!
