Multiple High Fertility Tests

Hey so I tested with the clearblue ovulation test multiple times. On October 31st and Nov 1st we were at the flashing smiley face and on the 2nd we had peak full smile. A week went by and I decided to test again on the 8th. We have had a flashing smiley face the 8-12th of November. I am due to start my period on the 17th. We are currently trying to get pregnant I just was curious as to why I am getting another set of flashing smiley faces so close to my period. Can you please help? We are not trying to get our hopes up but do really want to be pregnant.
