Early ovulation first cycle after miscarriage?

I had a miscarriage two months ago and this is my first proper cycle since then. I decided to step it up a notch and use clearblue ovulation tests this time round. I starting taking the tests yesterday , which is 2 days earlier then they recommended on the leaflet and today I got a flashing smiley (high fertility). Has anyone else had this where they ovulated much earlier than usual? Should I be worried that maybe something isn't normal with my egg and wait until next cycle to try again ? Thanks for any advice. Attached the photo of when glow thought I should be ovulating!
