Anyone have a positive opk for several days the cycle they got ++++

My LMP puts my due date at 27th Aug. However, I have long cycles. I had a positive opk on the 11th,12th,13th and 14th of Dec. Got my BFP on 24th Dec. I have my first dating scan next Wednesday but they said if I turn out to be under 11w I will have to go back for another scan. Because I had positive opk for 4 days in a row I am not sure if I will be over 11w.
