someone please help (Post Mirena mom)

I've got my Mirena removed on the 9th of August. Since it's removal I haven't spotted or anything. Slight brownish discharge when I wiped twice. About a week after removal other than that nothing. Once a week I've taken an hpt and just started taking ovulation test this past weekend. I just want to know how long it took for anyone to start ovulating normally. I had my iud for 5 years. No menstrual after 1 1/2 years. My ob said wait 6-8 weeks for everything to regulate. Just kinda concerned that I didn't know these things prior to my iud. And now I want another baby and don't know how long I'll have to wait. Please help
