I need to know i am not crazy! Yesterday i started having constant chest pain the moved through my shoulder and down my left arm. I thought i was having a heart attack! I went to the er the did ekg, blood work and CT scan. My ekg should a slip blip but had the same thing a few years ago no issues. My D Dimer was elevated. my heart enzymes were negative for heart attack. They said i had no blood clot in my lung! still having chest pain and no my period showed up 2 days early! Has anyone experienced chest pain before and during your period?? Thats the only explanation i can think of?? ALSO i had my nexplanon taken out in Sept 2023 due to excessive bleeding haven't had anymore issues will now!!
