Do these frequently have a evaps after time limit?

I took one yesterday afternoon cuz my cycle is a mess cuz I lost 20lbs recently and I thought I saw a faint line but then went negative and when I looked this morning there’s a pink line... and I feel like this has happened to me a few times with these tests! Annoying! But this one was darker so idk but I know it was out of the time frame for accurate results. Thanks
