late 10 days and ttc

An

i have always 28-29 cycle days

suddenly last month i was 10 days late

and this month i'm 10 days late and period still hasn't come

anyone relate ?

i don't think i ovulated this cycle because i didn't get a solid smiley on clear blue opk , i only got 3 days of high (flashing face )

it's annoying as i am ttc

any advice or explanation

or help ?

i took a pregnancy test negative

it's just annoying , i want my period so i can try next month again
