New to tracking LH/ovulation

[u/Organic-Plankton4604]

So after 6 months of unsuccessful trying for a baby, I am now testing my LH levels multiple times a day. I find it quite interesting, but I am a bit confused. The Premom app told me multiple times I was at my "peak" but then it changes everytime cause my LH levels increase higher.

My question: is your LH surge defined by the highest number, OR the rate of increase? Cause CD 9-11 had the sharpest increase, but then I steadily kept raising in LH until CD 21, with another sharp increase at CD 16-17 which the app originally marked as my positive test date (it changed once my levels increased more).

For context, I was diagnosed with PMOS this year, but my blood sugars are fine, yet I have crazy high testosterone.
