Semi freaking out for fearing I missed my window. This is my first time using OPKs but I've been testing since November 11th and had very faint lines. The picture here shows the 14-18th (today) and my lines are getting lighter. According to my apps I'm not due to ovulate until the 21st however my lines are already getting lighter. Did I miss it?? Or is there a chance it could get dark again??

UPDATE: really feeling like I did miss this now. This is my OPK from today and my line still seems to be getting lighter. Plus my temp chart is included. Also my first month temping but it all makes it seem like I ovulated sooner than expected. As I am getting closer to my "ovulation date" my tests are only getting lighter :(

What do you guys think?

UPDATE AGAIN:

After thinking I was totally out. I do my next OPK today and the line is getting darker! Time to BD??

After thinking I was out. Got my positive this am! Time to BD!
