I have pcos and was told by my naturopath I have parasites. I began taking serrapeptase 3 90000btu morning and night. When my period came, I passed a clot that was 5 inches long and approximately 3 inches thick. It alarmed me so I went to the ER where they said I was perfectly fine. It has been 45 days and I haven’t stopped bleeding. When I wipe there is constantly tissue and old/new blood mix. Not sure what to say. Does this mean it’s working? Harming me? No clue!
