Just had my ius removed

Hey everyone. I had my ius took out on the 28/7/15. Its been in for four and a half years. I want to try natural family planning but I've been told it will take some time for my body to adjust before I can chart correctly. I was wondering how possible it is to get pregnant after having the hormone coil removed. People talk a lot about the copper coil and getting pregnant but anyone know about the hormone one?
