How long should a positive opk lsat? please help!

[Minerva]

I starting the opk testing on day 15 b/c my periods are long and irregular. I'm using the BBT method and trying to chart CM but I am also trying to "have a girl" so I I'd like to stop trying before or around the time I get a positive surge. Weirdly, and for the first time, I got very scattered results from the opk and I am wondering what you think.

I thought the (2nd test) labeled Sunday Morning indicated the surge. But since it faded the same evening (and was faded the evening before) and wasn't quite as dark as the control line, I'm wondering if that was it????

My experience in the past is that I could get a positive result and confirm it the next day.

Just to agree, Sunday was the surge, but you must have had quite a lot of LH as it was still showing quite clearly the next day
