Why not much egg white is there a reason

Is it normal to have low firm cervix after your ovulation days ......just BEFORE your period is it normal .. just this month I've done cm checks every day .....

Well not long after my period I had low firm cervix and creamy

Then round my ovulation it went high and soft and creamy

Now it's low firm and very creamy

BUT NOTICE EGG WHITE NOT LONG AFTER MY PERIOD JUST BEFORE MY OVULATION DAYS AND DID A ovulation test AND HAD LE SURGE DAYS AFTER

WHAT WOULD BE THE REASON FOR NOT MUCH EGG WHITE PLEASE HELP

This is my Le surge and we had lots of sex so fingers crossed any help would be appreciated
