Finally a LH surge

This is the strongest LH I’ve had!! I understand it doesn’t guarantee ovulation. I’ve tied the clear blue monitor which said yesterday that fertility was low then tried this LH today and it’s high!? Unfortunately I’ve ran out of tests for the clear blue and ordered more so can’t compare.

I don’t understand why my clear blue said low fertility when it is supposed to be more accurate as it also measures Estrogen. All of this is so confusing!
