I would say so...but I have the opposite problem where my OPK only stay positive a day at most. Is it possible you miscalculated your O day and you are pregnant?
I've had 5 days of 'positives' before. I O'd on the second day of positives, based on temps. I put positives in quotes because I was using Rexall and FR and I seem to get way more positives on those than ICs or CB digis. They must be more sensitive to LH.

I've had 4-5 days before...I would say just a long surge but as RayRay007 said temping in conjunction will help determine O since temping is the gold standard and OPK the silver
