this kid is killing me!!!

I'm having insomnia issues. I go to sleep at about 11/12 & then wake up at 4 to a feeling in my sides and stomach that feels like .. Idk.. Sore? I go pee and feel a little bit better but then I can't go back to sleep & I constantly toss & turn. I stuff part of the comforter under my side and it helps a little but only for a little while. & this is random but seems like ever since I hit my 3rd trimester, my gas stinks really bad, anyone else?
