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 <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> to help me predict them, an so far so good. So please could anyone give me some help or experiences etc...
