Ovulation ???

Savana

My last period was Aug 17th-22nd

I believed I had ovulated on Aug 29th due to large amounts of egg white discharge with hence of pink blood. (Ovulation bleeding)

However today September 5th, I tested and got this.

I recently had my tubes reversed August 21st to have another baby.

I’m just so confused, I should be starting my period September 15th
