I didn’t ovulate until cycle day 27 this month !!
It’s so hard when your trying and testing and you expect the test to keep getting darker then suddenly it’s going lighter again 😭
There was about 36 hours where you didn't test according to your chart so you could have missed it then. Could still be coming. It's normal for it to go up and down
Sometimes you can miss the peak if you have a short LH surge. It can be helpful to keep an eye on cervical mucus as well to give you another indication of what's going on.
I don’t trust Premom at all. To me this looks like you haven’t hit your peak yet or failed to ovulate. Your body might try again over the next couple days x
