Everything seems to be related to peri?

Having 2 new symptoms here lately. Both of which caused anxiety initially. Phantom smells (thought maybe I was having a stroke 🙃) and I finally searched and saw it was a peri thing. The next new thing…last night while asleep I was awoken to my stomach cramping all over the place. Not extreme, but it was enough to wake me and not be comfortable. Not long after I started passing a ton of gas 🫣 and it was loud. I mean it was way more than I’m used to passing lol. I can’t think of anything new/different I ate and it wasn’t anything like greens or a really fibrous food. Could this be a possible peri symptom too? Or just a random food intolerance or something? Sorry for questioning everything. As someone with anxiety, something “different” tends to spike my anxiety. TIA.
