Confused about OPKs

[behappy1736]

I'm so confused 😕
Two of my OPKs were like this pic attached a week ago then came to nothing not a stronger line or anything but I did one today and it's just one test line you can barely see the second line! I'm pretty sure I haven't ovulated already as I have long cycles and on day 21 today but would an opk have some sort of line then no line if you hadn't ovulated?
Is it possible to have a line this these in the pics and then no line but you still haven't ovulated

Yes it's totally normal as there's always lh present in your body at low levels so two lines can be visible when your not ovulating . Some people like myself have elevated lh levels all month long so tend to get stronger lines even when not ovulating. It also tends to fluctuate during the month and varies from woman to woman.
One woman might see a gradual increase
Whereas another woman's readings might be up and down during the month .
When you peak your line will darker than control line .
Those tests are not positive. To me they don't even look like a high readings although you'd need to look at all your readings collectively to see that you haven't missed your peak.
Secondly did you take those photos immediately ? Give them a few moments because your dye window has not even cleared yet
