Looking for advice or if anyone had this too?

Ka

I had my last normal period October 15. 5 days all good, then spotting for 2 weeks after and now my period came a week early but only lasted 3 days (pretty heavy flow too) now absolutely nothing not even spotting. I took a test today because my period technically wasnt due until this coming Sunday, it was negative.

Anyone had this before? I told my dr and he said he doesnt want to do any hormone checks until it happens 2-3 months in a row 🙃
