I had this problem in my first
trimester, I had really bad trapped
gas it was so painful I would lay on my side just waiting for relief and it would take forever. I would try different positions to try and get some release but it only lasted my first trimester, by my second it went away thank god. Maybe talk to your doctor for any help, or look online for suggestions. I'm pretty sure there is stuff you can take to help relieve the gas.
