Faint opk

Kelly

Hi. Just wondering if anyone has any experience on falling pregnant while only getting faint opk. Iv done everything right and still not getting that dark line. I’m cycle day 16 and Iv had small cramping ect yesterday and today but my lines are still so faint! Just wondering if Pee not concentrated enough or what but it’s starting to worry me that I may not be ovulating or I’m doing something wrong. Last month was the same. Tia
