Surges and Peaks: Gradual Onset

There is a myth about LH Testing: most women expect they will only receive one positive result during a cycle. They are confused if they have more than one, especially when it lasts for a few days.  

Women who have multiple positive results have a  gradual onset LH surge.  According to a recent study, over half (57.1%) of studied women have this type. With this type, you may see multiple positive ovulation test results for more than one day before reaching the darkest line at the peak.  

There are three types within the gradual onset pattern:

TYPE 1: Single Peak

Some women have more of a steady rise and peak. In terms of LH Tests, you will see the test line gradually getting darker, rising to your peak, and then get lighter,  descending back to baseline.  


TYPE 2: Pleateau

There is a second type of gradual onset which is more of a  “plateau.”  In this case, you will see consistently positive results with similar darkness before ovulation. Not one line seems to stand out more than other lines. In this case, we suggest that you keep tracking until you see the test line begin to lighten again.  That day is your most fertile day, and your last positive of that cycle is your peak day.  


TYPE 3: Multiple Peaks

Still other women experience some dips during their gradual rise -- multiple peaks.  In this case, they may see several ups and downs in the test line darkness over a period of a few days.  They may be confused:

Which one is the peak?

Normally the last peak is the real one and signals ovulation is about to occur. In this case, you probably need to test two more days after you see a peak, until you are sure you’ve seen all of the peaks and the final decline.

This can be more likely to happen in times of stress, illness, or hormonal change, but these are not necessarily the only times.

If you have ever received two peak readings or a second lh surge in one cycle just a couple of days apart – you may have experienced multiple follicular stimulation.  What does that mean?

In order to achieve pregnancy, a follicle (casing and egg) is released from your ovary.  The follicle must rupture to release the egg.  In cases of multiple follicular stimulation, your body releases the follicle, but it doesn’t rupture. So, the egg is not released and you are unable to get pregnant. Your body realizes that this has happened and so releases a second follicle a few days later.

No matter what pattern you might have, remember that every woman is different.  Even cycles can be different! The best way to get pregnant fast is to learn your personal pattern through education and smart tracking.
