Anyone had a car accident delay their period?

Wondering if anyone else had a car accident mess up their cycle or delay their period? AF was due five days ago for me and didn't come and no positive pregnancy test yet.. i'm usually very normal with my periods and consistent. I was in a car accident with bad whiplash two weeks ago other than that can't think of what would cause this and am really worried about it. Calling my OB tomorrow but wondering if anyone has been through similar?

Side note- I had a hcg trigger shot the day of the accident and IUI the day after the accident , but not 100% sure if I ovulated or not or if they were affected.
