Is my opk testing positive for pregnancy?

So, I decided not to buy any pregnancy test until my period is due. But I'm weak and can't handle the wait 😫😅 So I decided for the fun of it to test with an Opk which I know can detect hcg. I am on CD21 and 7DPO. It was not positive but there is definitely something there, question is: can there still be remains of LH 7 days after ov?

What do you think? I know I will have to wait, but could this be an indicator?
