Did i miss my peak?

Hello everyone,

Just want a few opinions here. I'm very new to opk testing. I find these strips hard to read as the colour is quite faint.

My cycles are generally very regular (approx 30 days). I've been drinking lots of water which I know does not help with OPKs. I did not have a chance to test CD 14 morning as I was away from home all day, and I think may have been my high/ peak. Do u think I missed my peak around then? Tests got darker between 13- 15 and I had EWCM around then too which has dried up since. My test is totally negative today (CD 16).

Can I presume I have missed my peak here?
