Talk to Gynecologist on Vagina Extremely Dry

I have pcos and vit deficiency my doc recommended vit d supplements and since that day my vagina is completely dry.. We've been married for 8 months. I'm getting frustrated now my husband doesn't say anything he started using lubes but it's getting too much for me.. I've never needed lubricant in these month but suddenly I'm not getting wet at all no matter how much foreplay. A doc says it's due to lack of sex drive or foreplay etc aurton mai aise hi hota pain hota hi hai etc but I want some solution due to which I'm posting here.. Can someone suggest something for it? Some remedy or food
