I had the mirena and it was taken out July 24th 2013 and nothing has happened yet. I have had 1 round of clomid and go for blood work on Monday 7/14 which is my day 21 to see if i ovulated and maybe show that im pregnant. Im praying i am this time round but if im not ill take clomid again after i have my next cycle.
I had this same question and yes most people say it should not take long. But I got my iud (no hormone one) removed in November 2013 and been ttc ever since and nothing yet :( hope I get lucky this month and Aunt Flo stops coming.
Almost immediately as I was on iud ( copper), I'm 7 weeks but every women is different. Hope this helps, good luck best wishes for the further. Xx
