Temperature or LH test to detect ovulation?

[LaLune85]

I’ve been using the Natural Cycles for 2 years now and trying to conceive. I monitor both my body temp and LH levels but I was wondering which was the best indicator of ovulation. Quite often my LH will show I’m about to ovulate but a few days later after the app’s algorithm has analysed my temperature it changes my ovulation day to a day or so prior to my LH spike. As far as I was aware LH spike happens a day or so before ovulation. I’m confused as the two indicators don’t seem to match up. I’ve also read that body temp can change depending on sleep as well, and I know my sleep fluctuates a lot. So I’m wondering if I should disregard my body temp as an indicator? Any one else have experience of this...?

I do both - I ovulate the day of my positive opk which isn't typical. This cycle I had a temp drop and a positive opk later that afternoon followed by a big spike the following day.

I'd say temperature is a better measure to confirm ovulation - opks just measure that you're gearing up to ovulate. I think the only accurate way to really tell is a blood test.

Temp is meant to be more accurate as you can have multiple LH spikes during a cycle or LH spikes that don't result in ovulation (just your body trying to). However - this is on the assumption that your sleep is undisturbed, take temp at the same time, that you're not ill or haven't been drinking. If it's an oral thermometer then how you take the temp (closed vs open mouth, under tongue etc) also has an impact.

I also don't know how accurate Natural Cycles - would it be worth plotting the data in FF for a cycle and see if the predictions match up?
