Wondfo ovulation tests - evap line?

[tarheels]

So I'm CD4 and just took a Wondfo to do a control stick. (I used the expensive digital last month and wanted to switch over to these.) There's a faint pink line...like if this were a pg test, I'd be jumping up and down.

I noticed on these instructions (unlike the Wondfo pg test instructions), it says that a faint line is a negative. Any experience with this? It has got to be scientifically impossible to O on CD4, but with my wonky period with a week of spotting beforehand, maybe I got the CD wrong...? Please tell me you get a faint positive with the Wondfos and it really means negative like the instructions say! DH is OOT, so we can't just BD JIC.

The test line on an OPK has to be as dark if not darker than the control line for it to be a true positive (the opposite of a HPT, unfortunately, where a line is a line). From what I understand, many women have a small amount of LH in their systems prior to the surge at O, so that's why a faint line may appear.

Yep, ditto PP. Most women will always have a faint test line. The line needs to be as dark or darker than the control line to be positive.

This is what I do (and as usual, it makes me look crazy town) - test every day from about CD 8 until O. I'll test twice a day once I start to get close. I keep all of my tests along the way and arrange them on the counter from older to most recent. This way, I can see the progression in the darkness of my line and get a better idea of when I am approaching O. For example - I just tested for about 5 days in a row, and had lines that were all light, and the same. Today was the first day that the line got a bit darker, so now I'm on to testing twice a day until I get a positive, and then a negative. (Yes, I know that the tests are only supposed to be read immediately, but this seems to work for me)

Ok, thanks. Not crazy, not Oing, good to know lol.

Yeah, jewel, what you do was sort of my plan. Keep them to compare them, hence the early test when I was definitely NOT ovulating to compare later tests.

I pretty much always have a faint test line. You can usually tell when it is positive- it is very dark.

You should definitely notice some "fade in" as long as you start testing early enough. When the test line is as dark as the control line, you're about to O :-)
