TTC after mirena

Leanne • Mom to a fantastic 6 1/2 year old boy, married my best friend on 4/17/15, TTC as of January 2015.
Had mirena taken out on January 19 - after 5 years. No sign of anything yet and I just don't know when to expect my period because I didn't have one while on BC. How long did it take yours to come back?
