Here’s how mine looks this cycle. Similar pattern, goes up and down. I think if you have 3 consecutive days of temps above your cover line then ovulation is detected but I may be wrong! X

Yer that's a bummer, mine went dark then light often this cycle. Finally got a for sure positive today on cd18 defo drove me crazy! I'm posting my chart so you can see it. Just to compare so u can see honestly it's always different. You'd be lucky to have a persistent pattern each cycle xx

No i did over 30 last time before taking provera and no positives test line not dark enough maybe one positive but wasnt sure

That's a possibility Hun, charts can change going by temps states anything you've input into your chart can cause changes, even ewcm after ovulation can affect confirmation of ovulation. Keep us updated Hun xx

So this morning my chart is back to confirming that I may have ovulated on Friday 🙈 I can’t keep up- I’m sure it will change again tomorrow 🙄
