LH surge questions! OPK faint lines for 9 days

Ok... so I've been testing for 9 days now. First day, there was absolutely no line. Starting 2nd day there's was a very faint line showed and got darker as days went by but still not as dark as the control.

My husband and I worked hard in bed -_- every other day and OPK stick still shows faint line. It is just not going away...

So still impending surge?

Am I conceived? (Hasn't been 2 weeks for hcg test)

How long after conception does lh level drop?

Thank you for reading and your time!

Good luck to you all!
