Symptom narrative

Same as last year, after getting Pfizer Covid shot this year, I immediately started my period that lasted for weeks. Note that I got the Flu shot separate this year, back on 10/28/25, to see if that would help. Also, I scheduled the Covid shot close to when I was supposed to start my period (due to this happening last year), but still started a few days early as soon as getting the shot (literally had shot at 11am and started spotting at 3pm that same day!) and it lasted 3-4 weeks long, which is Not normal. For next year, I?m thinking of switching back to Moderna or to the non-mRNA option.
