Pregnant after being in Cuba

So I'm currently 7 weeks (according to app) and when I calculate when I must've conceived, it was a week after I was in Cuba. I'm really scared because I took all precautions during my stay and after I came back due to the Zika virus and still became pregnant! When I got back, I called the healthline and the nurse said I should be okay because I didn't have any weird mosquito bites or fever, but I haven't had my first ultra sound yet or informed my dr. about it. Just wondering if anyone has been in a Zika area and all was okay?? Thanks!
