A Couple Of Weeks Ago, I Started Taking Antibiotics For

A couple of weeks ago, I started taking antibiotics for a sinus infection. While I was taking it, I realized vaginal dryness is one of the symptoms which I experienced but ever since then it has been uncomfortable having intercourse. It has been irritating down there and even burned when we used a little bit of lubricant and there has been an odd odor from some days. Is this something I should worry about?
