TTC following IUD

I had my iud out on the 3rd and spotted for a day and a half. I had a period starting the 6th for 5 days. Glow says I should ovulate on the 21st but how accurate is that since my body is coming off of the Mirana iud? Has anyone conceived that soon after an iud? I have VERY irregular periods and never ovulated without medications before my LO but doctor said having my baby could have regulated my body.
