No feeling good

Today when I woke up, I have not been feeling good at all. I used the bathroom a couple times, my stomach hurts and feels weird like it’s giving me anxiety in my chest. Gotta little back pain as well. I been hoping my period is coming because as of now I’m 2 weeks late. I have taken pregnancy tests but they have been negative, I’ve taken the tests after my missed period so I know I’m not pregnant. Just took some pepto I’m hoping it helps
