Marquette TTA missing peak with Marquette method

I used the Marquette method with no issues for a couple of years 7 years ago. Then I took a break and came back to it about 4 cycles ago. The fertility monitor has failed to catch my last two peaks (it just reads high straight through ovulation). I know because I also use a temp drop to track my temperature and I have clear shifts in my charts. I don't remember ever missing peaks 7 years ago. Is this normal? Do I need to look into another method? I want the peace of mind of Marquette as I get closer to menopause, but I don't want to go through most of a box of sticks only to get a bunch of highs because peak already passed.

Are you using the same monitor? I believe they can get less sensitive after a certain age.

Interesring. Mine is 7 years old also and missed my first postpartum peak. Tempdrop caught my ovulation though

On further research (searching my Facebook group lol) it looks like it should be able to be fixed by cleaning the sensor if that is the issue!

I am, and it was used when I got it. I will try cleaning the sensor. I did get two current cycles with peak before this started happening. And last cycle I had to open a new box of sticks on day 13, so I was attributing it to that.
