TTC after mirena iud, has anyone had any luck?

I got mirena removed on 1/20 I am going on my 3rd month of ttc. had regular cycles in jan and feb, but a goofy one this month but still no bfp and I also have not had cramps like i did in the past months.. how long did it take you or how long have you been trying since removal? Help I am starting to wonder if having mirena was a mistake because with my other kids I was only off the patch for 2 weeks before getting preggo, but now it is going on 3 months. So anyone have any success stories or horror stories to share with me? Help please!!
