positive opks. but not ovulate?

could you have positive or a almost positive opks, but not actually ovulate?

The reason I asks is because I haven't had a postpartum period since having my son almost 6 months ago, but have gotten what I would consider positive(or almost) opk. Could I still ovulate without having had a period?
