Soooooo confused need help!!!

Stephanie
I started taking my opk last Tuesday! My cycle is 37 days because of a MC I had nov 8. I had a positive opk last Wednesday and have had two lines in each test I've done! I take test at one pm and 6pm! Am I doing something wrong? Why are they all coming out positive? I'm due for AF on December 14th from what glow said. But normally my periods are 3-8 of the month.
