TTC after IUD.

I had my IUD removed in December '16 after 4 years. I had no period while I had it in.. not even a spot. After having it removed in Dec. I had a normal period in March and then a gawd-awful 2 1/2 week period in April. I honestly lost 7lbs that month and I wasn't even trying. Then I didn't have another period until Sept. 15th. And although it only lasted 7 days, it was SUPER heavy.

I originally had the IUD removed because my husband and I want to have another baby, but now I'm not sure if I should even be concerned about TTC until I get AF to visit on the reg.

Anyone have anything similar happen after an IUD?
