Is It Safe To Get IUD At Age Of 19?

Hi, I'm studying abroad in New Zealand with my boyfriend for the next 4 months. We've been together for a year and we're both virgins, but thinking about changing that. I've heard that going on and off birth control and switching pills a lot can affect your fertility down the road so I want to be careful. I was on Ocella for about 3 months 2 years ago. Also, I want to be able to get something here that I can also get in the U.S. so I don't have to switch when I go home. What about an IUD? Is that an option for my age? I'm 19.
