Stomach pains

So this might be nothing, but is it normal to have stomach pains like where it feels like you've got a giant gas bubble in between your throat and stomach. I'm just over 14 weeks pregnant and have felt like this since yesterday. Eating and drinking don't help it. :/ Any advice would be great, I'm dealing with so much stress, depression, and anxiety as a first time mom already. I'm constantly nervous that my baby isn't doing okay and stressed working as a first time teacher. I just don't know how I'm going to do it :(
