So I've been using cheap LH tests and they've all been stark white until yesterday morning which was fairly dark (maybe 70% as dark as the control line).
I figure I'd then get a darker line in the evening but it was fainter and this morning there was hardly a line!
Normally my line darkens over a few days, peaks and then gets lighter over a couple of days.
What's with this super short surge?
Not sure if it's relevant but I had a miscarriage last month.
