Gas issues during pregnancy

Has anybody dealt with extreme gas issues during pregnancy?

I am 13 weeks and basically since the beginning I have had trouble passing gas and having extreme gas pains and bloating. When I do burp it’s deep and my sternum aches and passing gas is happening less. I have a lot of pain in my back in my right side up by my shoulder blade and in my rib that comes and goes but I have it more than i don’t. I’ve talked to my ob and my primary and they both believe it to be from the gas and from my GERD. I am taking nexium and gas relief pills when it’s really bad and tums.

My primary did think it could be my gallbladder but I had an ultrasound done and they said it looks fine.

It’s getting to the point that it’s always effecting me and I’m uncomfortable all the time. And with it being my rib and back area and having bad anxiety I am always worried it’s my lungs but my dr said it seems muscular not internal.

Any advice for anything I can take or chance to help get some relief?
