Weird chest feeling

I’ve been having a weird irregular chest feeling, not a pain more just a discomfort. I can breathe in and out fine. I ran around in the yard with my daughter no issues. Did a little workout. No issues. I do have anxiety. I am due for my period soon and on birth control. Could this be anxiety or heartburn? Maybe even gas. Could I possibly have a heart condition ? It’s not one sided more in the middle between breasts or right under. Slight feels like an ache or burning. 🥲
