Continuous High Readings - Fertility Monitor

We're glad you're using the Clearblue Fertility Monitor, Ksenya.  Some possible reasons why Peak Fertility may not have been displayed include an unusually short or long cycle, if a test was inadvertently missed, or if you didn't ovulate during these cycles.  Since this happened two months in a row, we'd like to talk through your questions.  Please call us at 1-800-321-3279 and mention reference #FB557.  We're here to help Monday through Friday (excluding holidays) from 8:30am-5:00pm Eastern time.

In addition to the reasons that Karen suggested above for missed peaks, I have a few suggestions too.
You may also want to switch to afternoon tests instead of morning tests, using urine that's sufficiently concentrated (you shouldn't have peed in the 4 hours prior to peeing for the test, and shouldn't have drunk a lot of liquids in that time). Because LH often rises in the wee hours of the morning, for some women it might not have had time to accumulate in the bladder in sufficient concentration to trigger a peak reading by the time of the first-morning-urine test. And it may have dissipated by the time of the test the next morning. Some women have better results switching to an afternoon/evening testing window.
Or, perhaps your LH levels are not high enough to go over the monitor's pre-set threshold for LH. This is the case for a minority of women. The threshold will work for the majority. but not all. CBE has a more sensitive device out: the Advanced Digital ovulation test. This measures estrogen and LH, too, but the peak display will come when LH rises significantly above your personal baseline levels. A more sensitive test could work for you when the monitor does not.
If you've been peeing straight on the stick, you could also get better results if you pee in a cup and then dip the stick for a *timed* 15 seconds. Peeing straight on the stick carries more risk of missed peak if you inadvertently undersaturate or oversaturate the paper.

I hope this helps.

I’m kinda the same I had 10 days high showing, two days peak then 2 days no showing and I’ve been showing high for the last 10 days and four of those I’ve experienced what I’m pretty sure is my period. Does anyone have any advice towards this. I’m 37 and really don’t want to wait around.

Hi Melissa,

Your results are what we would expect tosee if you carry on testing after Peak Fertility.  There is a second risein estrogen after ovulation so it’snormal to see more High Fertility days if you carry on testing afterPeak, High Fertility will then continue to show once found.   There is no value in continuing to test after you first seePeak Fertility – you have found your most fertile time.  You can save anyremaining test sticks to use in a future cycle if required.
