So I've been using 2 different OPK's, Clear blue advanced and a drug store brand. I've been testing every day for 4 days and now I'm just confused. It looks like I got a positive LH surge on the drug store OPK (the test line is darker than the control) but my digital test is flashing (high fertility) saying that it hasn't detected my LH surge yet (peak fertility). The clearblue uses a blue dye and the drug store brand uses pink dye.

Has this happened to anyone else?

Are the paper/plastic test strips more effective than digital?

Does pink dye work better than blue?

Sincerely,

Newly TTC and confused asf

It's hard to tell in pics but left is darker
