Help! Never done this

Morgan

Hey everyone, ive never use OPKs and I am only day 10 but i got a positive reading, wasnt meant to ovulate until the 29th but now its all changed and to me and what tests ive seen of others the lines arent dark enough to be at peak. Can it be wrong? I know i tested early this morning but I have soccer with my other child and wont be home until 4pm
