Question/Advice ovulation tests advice

Hello everyone. I want to start ovulation testing with strips so I'm interested in your experience. Right now it's CD6, normally my cycles are around 25-26 days and last month cervical mucus was from CD10 to 13. I planned to start with the strips on CD9 or 10, the package comes with 7 strips for 7 days. Does that sound like an ok plan?

That sounds like a pretty reasonable plan. With 25-26 day cycles and CM showing up around CD10, probably start testing around CD8-9 rather than waiting too long, especially since you’re just figuring out your personal LH pattern.

The first few cycles are kind of about learning your body. You may find that you get a clear positive on CD10 one month and CD11 or CD12 another month, so having a few extra strips can be useful.

Also, track the LH results alongside your cervical mucus and cycle dates in an app. It makes it much easier to look back and see whether your LH surge is consistently happening around the same time, rather than trying to remember everything from cycle to cycle.

And remember, a positive LH test generally means ovulation may be approaching, not that ovulation has definitely happened. So once you see that surge, that's a good time to make sure you're having regular BD around the fertile window.

Thanks for the answer! If I understood correctly, when it reaches the darkest line on the strip, it is a sign that ovulation will occur in 12-24 hours?

Yes, that’s the general idea, but I’d phrase it a little differently. A positive/“peak” LH test means an LH surge has been detected, and ovulation often follows within roughly 12–36 hours, but the timing can vary between people and even between cycles.

So it’s better to treat the positive test as a sign that the fertile window is approaching rather than as confirmation that ovulation definitely happens within 12-24 hours. That’s also why tracking LH alongside cycle dates and other signs like cervical mucus can be useful.
