Positive opk for 6 days!

Lyss • Expecting 5-7-16 💙
So I have been getting strong positive  ovulation test for 6 days now. The test line is a lot darker than the control. This has never happened before. I don't think I could be pregnant bc I got my period March 5th this month. My right side also has been cramping and achy. Is this normal to ovulate and get strong Lh surges for this long. This is my first month consistantly taking opks and in the past I could never even get a positive. Is this something I should wait out or call my obgyn?
