Hi. I've done an otk over last few days and line has been gradually getting darker. Today's one is the darkest so far but still not sure if I'm ovulating yet or not. Can anyone else tell me what they think please. Here is a pic of today's test stick.

I'm not sure if the test line is still lighter than the control line. If it is then packet says it's negative but I'm not sure and done want to miss my ovulation window this month. Thanks
