Solid Smiley Face for 1 day, Day after started my period

Hello everyone I’m wondering if anyone can help?

I recently went through a miscarriage on 11/09 myself and my partner decided to try again beginning of Oct however bearing in mind I hadn’t had a period after I miscarried

I used the clear blue ovulation test and continuously had flashing smiley for 13 days however yesterday (14/10) received my first solid smiley face however today (15/10) I started my first period since miscarrying
