If the test line is as dark as, or darker than, the control line than that is a positive OPK and you should be ovulateing in the next 12 to 36 hours. I hope this helps, good luck!
The line on the left should be the test line, while the line on the right is the control line. To indicate ovulation you need the line on the left to be as dark as or darker than the line on the right.
Did you read the information that came with the test kit? Your question is worded in such a way as to make me think you don't understand the whole concept of ovulation.
