False positive or bad strips!?

I’m on cd 16. 3rd round of clomid and I haven’t got even a flashing face on my opk which for me at least is unusual. So today after another blank on my opk and I said F IT! And dipped in a HCG test then I was like umm excuse me??? So there went in another one and another?! WHAT IS GOING ON!? They have faded after 5 mins but on the box it says anything after 3 mins is a no go. I’ve already had my period. I’m so confused.
