Egg white cm early

Pavi

Hi i glow says i have 33 day cycle (average though, its 31 to 34) so i always ovulate like CD 17 , 18.

Now glow says i ovulated on 21st of this month. But i got egg white cm with cramps on CD 10,11 which is on 14th/15th of this month..

Is this really possible that i have ovulated early. I dont remember ovulating early. We did BD.

But curious if i really have ovulated early. Seein others post pics pf egwn i can say its exactly ewcm.
