Comparing Tests

I started testing on Day 9 and did what the instructions said to do and didn't test with early morning urine. It is supposed to be as dark as the other line but I haven't gotten that yet. I am now thinking that 1/19 and 1/20 was my surge. We BD on the 16th, 19th and will again tonight, but I'm scared it might not happen this month because I didn't read them correctly! What do you think? ​
