Strip tests

Can someone help me please? Had my peak on clearblue yesterday (static smiley) around 9am, strip test was negative. Last night around 7:15pm I had mild cramping and backache, so took a strip test and it was a bit stronger than the morning test. BD’d around 9:30pm.

This morning I woke up and took a strip test around 9am and the first two pictures are the results of that strip test.

Did another one this afternoon around 3:25pm and they’re the last pictures.

Could someone maybe shed some light on what could be happening please? My CM is runny and stretching between my fingers but is a little cloudy.

My app says I’m due to ovulate tomorrow. Have I already ovulated? Am I too late? Is this normal?
