Double ovulation or fluke

Kathryn • Married💍Mom Of 4- 18, 16, 5, 9 months

I had a positive opk on the 7th.

Waited and now it's the 22nd and ive had VERY HEAVY crystal clear ewcm for 6 days... its like a slip n slide....😵

So i decided to humor myself and take another opk since I have been getting negative pregnancy tests. It was a BLAZING positive.

Has this happened to anyone else and then gotten pregnant?
