Genre?

Genre. 
I'm calling on other writers to help me out here.  I have no idea what genre I fit into.

The history of how I came to what I write about starts from when I read Little Women as a child.  I had a huge imagination, and like Jo, I wrote fantasy based stories.  When I read the professor's advice on writing what she knew, it got the wheels turning and I actually stopped writing.  I figured a teenager growing up in suburban Wisconsin didn't have much interesting material to write about, so I went about my life seeking adventure.

I took a course to be an emergency medical technician (EMT) when I was 19 and worked in the inner city of Milwaukee for a couple of years, and did ski patrol on the weekends.  I backpacked through Ecuador, S. America when I was 20 for a month, and then got on the waiting list for nursing school at the local tech college, and moved to Ecuador for 10 months.  I ended up staying for three years instead, and lived in three different locations including the rainforest.  I fell in love and married my husband, and then we both moved to the States so we could pursue education.  I studied nursing and he studied computer programming.

Now after all these years, I'm back to writing.  Although I'm not Hispanic (funny thing is I look more Hispanic then my husband because I'm 75% European descent and 25% Philipino, AND I speak fluent Spanish now), I know a lot about the Hispanic culture because of living there, my husband, and my friends.  So that's what I write about.  My WIP is about a young American woman who travels to S. America and is inspired to study nursing and return as a volunteer.  She ends up in the rainforest in a small town where she discovers they are growing cocaine.  The government steps in and puts an end to it, and the cartel seeks retribution.  Oh, and she falls in love with the doctor running the clinic where she works.

So, what genre is that?  Mainstream?  Romance?  Help!  I'm so confused.

Then so I can get to know YOU better, how did you end up in the genre you write in?
