How long do i have before I ovulate

Hi ladies,

We are TTC#1 and have been trying for like 2-3months. I am hoping to get pregnant this month. I took ovulation tests from dollar tree for the first time.

The first picture was taken around 11:15 yesterday and we dint had sex yesterday coz we were busy.

And the second picture was taken today around the same time. How much time do i have before i ovulate this cycle

Any advice/comment please

Took the test yesterday

Todays test
