Mirena removal and ttc

marie
Hi, I had my mirena iud removed in November 2015 and have been trying or not preventing for ttc...I've read alot on here with people trying ttc after removal of mirena and not being able to. Does anyone have any suggestions on what they did? I have one already and i don't want my son and baby to be really far apart in age and hes already 7. Thanks in advance
