I’ve noticed the last couple of cycles that my LH surge has been much shorter. This month has been the shortest so far and I wanted to post some pictures to show how easy it is to miss your surge if you follow the traditional instructions.
OK, so opk tests tell you to check once a day from a few days before your expected fertile window. I tend to test around 2pm as you don’t have to use FMU.
So here are today’s and yesterday’s opk tests:
Both are clearly negative, right?
So, if I was going on these alone, I’d be assuming my surge hadn’t happened and then I would get a temp jump and say WTF? I ovulated without even getting a surge this month!
But then look at what happens when I test more than once every 24 hours:
There’s my positive – in the middle at 7am this morning. Note that these tests are now dry, and the lines were all darker when they were read within the limits. The middle one was clearly positive this morning (although it does look borderline now).
So there you go.
How can you make sure you don’t miss your surge?
- Test daily, at the same time, from around 6 days before you anticipate ovulation.
- As soon as you see a line that is slightly darker than the first test you took, test every 4 hours (3 times per day).
- Don’t worry about how much you drink, or how long you hold: I’ve drunk litres of water before testing and tested an hour after the last go and the surge still shows.
- Remember that the surge may happen 2-3 days before ovulation, or as little as 12 hours before ovulation.
Two and a half years of opk fun condensed into one post.
