Trauma & Ovulation

Je
Hi!
My husband & I are trying for our first. While on a run, I tripped on a rock and fell. I almost fractured my ankle! Luckily, it's a sprain. That morning I had taken an ovulation test which came back as high fertility. The next day I expected to see high fertility again, or maybe even peak fertility. Instead, I tested low fertility & have for the past few days. 
Does trauma to the body delay ovulation? Has anyone else experienced the same thing?
