How long after you discontinued your birth control did you ovulate or get pregnant?

Tori • Hello Glow! I am new to this community. My husband and I have been together for 5 years, married for 3 and are TTC baby #2. We hope for a boy, but will take a healthy baby overall of course.
I had my Mirena IUD removed on June 16th. During that time I was spotting. I had my IUD for 6 years. We are anxiously wanting and trying to get pregnant by the end of the summer. Is this a realistic goal? I am tracking everything here on Glow, and it says I should start my fertile week tomorrow. I am extremely new to all this. I didn't have a period for 5 years. So I have lost track of when I did ovulate. Does anyone have any pointers?
