Concerned about pregnancy

Br'Sade
I had the mirena removed on 12/1 after having it in for almost 3 years. I had it removed because I was having complications I had gained 40lbs since it was inserted after my son was born 2 years ago and I was continuously spotting and it had began to move around and I also became pregnant and had a miscarriage while it was still in. My doctor told me she didn't see any scarring that would cause me to become infertile or any long lasting problems. Me and my fiancé have been having sex all throughout my fertile period. Normally I would began to feel symptoms of AF coming by now. Has only one on here gotten pregnant right after they have had an iud removed? I have seen a lot of things online saying that if you get pregnant after it is removed you will have a miscarriage
