Opk help

Can someone help I'm trying the sperm meets egg plan and it says cycle day 10 start testing ovulation... For the last 4 days since cycle day 10 I've had a faint pink line which is negative as the line has to be the same or darker however I have done want today cycle day 14 and there's an even fainter line.. Last month I ovulated on cycle day 30.. Could I still ovulate or have I missed it
