Tracking Ovulation

Hello! I've been tracking my ovulation and I've just been waiting and waiting for a sign it's coming. Can someone tell me if I've possibly missed it or if I should just keep testing? I started Metformin on Tuesday so hopefully that helps regulate things even the slightest. Also, if you've had similar cycles could you post your tests? I'm a little confused on what EWCM looks like because I've seen many different types and it's a little frustrating not knowing what to look for. What I'm having now is very tacky like glue I suppose.
