sharp pain in rib cage

crystal
Im currently 30 wks but almost since the beginning of my pregnancy ive had this sharp, very uncomfortable pain in my right rib cage. My Dr. has said its because of acid but ive tried almost everything and nothing has worked for me and he doesnt seem concerned but the pain has just gotten worst. Im just curious as to if anybody else has experience this and what have they told you it is. Any info would be greatly appreciated and extremely helpful. Thanks in advance
