Positive OPK??

Hey ladies! I believe I got my positive opk yesterday and my hubby and I did the BD last night. I know it says to stop testing once you get a positive test, but I took another one today and both lines are the same color but very light. Does this mean it is still detecting my lh surge and I haven't ovulated yet? I had ovulation twinge on my right side and light cramping yesterday. Just wanted to see if anyone else had experienced this. We are going to BD tonight and tomorrow just to be sure ;)
