@Charley cycles are anywhere from 28 days to 50 days, I have PCOS so they’re quite irregular. I do use Premom but also wanted to keep them on paper as I know lighting can affect the readings on Premom sometimes and I wanted something to refer back to as I usually dispose of the tests after recording on Premom. Somewhat easier to see the lines change when they’re right next to eachother on paper!
Ah so if this was a 28 day month you'd expect to be ovulating now but if it's longer then you'll ovulate later. With pcos its hard to know but generally you won't ovulate until 2 ISH weeks before your period. I'll be honest keeping them is less helpful than you think, they are invalid after the reading window so looking back to refer to them might not be helpful. If you're lining the tests up with the template on premom then it's pretty good
How long are your cycles normally? Have you got a screenshot of premom, if you've got more tests on there it's better to look at that. The app exists so you don't have to stick them down like this!
