OPK frustration

Ashley

So I am on day 25 of my cycle, been testing since day 9, and still have yet to see a positive OPK. I have been testing 3 times a day this past week just to make sure I don’t miss my surge if it decides to show up. Here is the last OPK I took and pretty much the darkest I have seen so far... Anyone else not get a positive throughout their cycle? This is the first month TTCing and I never kept track of my cycles, but I generally get AF every month probably within about 30-35 days typically.
