Negative opk the morning after Positive opk

Michelle • TTC baby #2&3

Ok so on CD 11 AM I got a vvfl, CD 12 AM I also got a vvfl, CD12 PM I got the darkest Positive I’ve ever received on an opk, today CD13 AM glow called it Negative, any thoughts on this? Does this mean I am still about to ovulate?!

Keep in mind I received two low readings on the clear blue digital advanced tests and my temps have continuously dropped to 97.16 today..

TIA
