How long can it take to conceive?

So I was on the implant for 3 years and 6 months. I had it out sometime in April this year, me and my partner are trying for a baby. I'm 18 and was wondering how long preferably it could take for me to conceive. As I never had periods on the implant I'm now using the glow app to help me predict them, an so far so good. So please could anyone give me some help or experiences etc...
