Opk help

Ch

Ok so Im in my fertile week and the past 3 days I’ve gotten positive tests (I usually only get one). I took one this morning but the lines are so faint I couldn’t tell if it was showing an oh surge or not. I’ll post all 3 tests for the 3 days as comparison.

Day 1⬇️

Day 2⬇️

Day 3(this Am)⬇️

Is this still a positive?

Thanks in advance.
