dryness after period

I'm wondering whether anyone has this problem and what I could do to help. Since going on the contraceptive pill, once my period finished I get really dry. Not just during sex, like all the time and it gets quite uncomfortable at times. I'm also prone to yeast infections so can't use any feminine products that  may cause those. I've always had a problem with getting naturally lubricated during sex and when I use Tampons during my period but it wasn't all the time.
