Need some help i’m so confusing...

My cicle goes between 30 to 35 days. I entered all the information on glow. I’ ve been following since june this year.

TTC from same month. With no results even if BD almost each day 😆. Then i read that it could happen that not every month we ovulate. I did not took any test back then to know if i do or dont. And got my period late this month 2-3 days late than glow told me. Fine....

So i bought a ovulation test. Wich came with 9 sticks. Glow told methat i should ovulate around 30th july. And because my periods are long, i should try testing from day 16 of my civle. So i did early. Today 23th july y took the test and came up to this.

So thats means i’m ovulating within 24-36 h . Entered this info in glow and everithing change, all my cicle... should i believe this test? Or take another one?
