Flashing smiley face on OPK 7 DPO

I don’t know why I wanted to pee on it I just did. 💁🏻‍♀️ and I have a flashing smiley face now. What could that mean? Can you randomly have surges/ influxes in your luteral phase?

I confirmed a peak day about 6 days ago but since it was my first test this month I don’t know when exactly the peak started so I could have been at the beginning of it or the end of it. Regardless I had plenty of sex prior and after.

Could this be picking up some hormones from implantation? I don’t know if the test are strong enough for that!
