ttc after Mirena removal

Hey everyone. I had my mirena removed a month ago and am desperately trying to have a baby with my finace. My first 2 children were with someone else and we got pregnant significantly fast. However this time I feel like it may be completely opposite. I guess what Im trying to say is:
How long did it take to conceive after Mirena for those of you who have experienced this? Like I said it was within a couple weeks of a mirena removal last time... and it had been in for 3 years. I only had the last one for a year.
