OVULATION HELP

Safari

At 9 AM, I got a digital smiley “peak” day, took out my stick and it had two dark blue lines. YAY! But then later tonight, at around 5, I took another one, expecting them to be just as dark or darker, and it was faint. (Second pic!)

Yesterday it was faint too. Does this mean I didn’t ovulate? Was my LH surge not strong enough to trigger?

Any experiences / insight would be helpful!

TIA!
