Clomid, waiting for ovulation conflicting opks ✨🤔🙄

Can anyone offer a bit of insight? I had a positive on clearblue digital this morning but the cheapie didn't look positive, then an hour later cheapies looked darker but still negative now it's pretty light again and clearblue is negative, what is going on?

I also had a dip in my bbt chart this morning which is very unusual and clearblue advanced has shown high fertility for 3 days.

Today is day 7 after finishing clomid and I'm told I should ovulate between now and friday
