Don't worry. Sometimes, the 上深下深 only appear a few hour ga ja. So you may just miss the time je. If the line is nearly the same, you may check it a few hours later, then it may become 上深下深 ga la. And it may appear only a few hours, so may be the next day you check, it become the same as day 15 la.
Also even you never see 上深下深, it doesn't mean you have no ovulation ga. It is just an indicator for the LH surge, some ppl have no LH surge yet they ovulate ga. Don't worry sin la.
