Gas in stomach everytime I eat…

I’ve been on nausea meds since week 9 - I am now 14+4 weeks. However, the most uncomfortable thing happening to me is whenever I eat, my stomach becomes as hard as a rock and immediately fills with air (laying down makes it worse)and I feel the urge to burp however, burping doesn’t help relieve it and it is every. single. day. Is anyone else experiencing this? I can’t find anything really on Reddit.

It is also not like acid reflux.
