Ok,
A friend has become pregnant (lovely) so gave me her OPKs. Have used my own the last few months and put info into an app.
The ones she gave me have the 3 faces -empty,flashing,solid. Ones I've had before just empty to solid.
Tested yesterday morning (possibly after only 4 hour hold as went for a wee in the night) and it was empty.
Tested this morning and it was solid.
No flashing, just solid.
This is pretty early for Ov according to my app. And I'm confused as to why no flashing unless my Lee yesterday wasn't strong enough (but also the few days before it's been empty).
Would the "reader"'remember her levels from when she was testing and therefore it could be inaccurate? Or is it not clever enough for this and is it just that my levels have gone from nothing to peak peak with no in between?
