When to count as cycle day 1?!?!?!

KT

On my 2nd round of Letrozole 2.5mg.

My first round wasn’t successful and I was given provera again to start my period. I’m on my 2nd day of provera and started having dark brown blood discharge.

Do I count today as my day 1 of cycle? My doctor told me before that any blood that comes out count as day 1.

Thanks!
