Its not always easy hun, my OH and I weren't trying, but it was still about a year and a half between coming off contraception and me falling pregnant.
Especially if you've been on the pill or had the implant or something like that, I think they say that it can take up to 6 months for the pill to clear out of your system.
You're young, you have plenty of time. Enjoy each other!
Good luck for the future
