Pregnant. Back from 9 months RTW & worried about Zika

My partner and I have been back a month from 8.5 months of travelling 14 countries around the world 12 of which are Zika affected and boy did we get bitten along the way. I mean attacked. I've been alternatively using the patch and pill but have found out I'm just about to be 5 weeks pregnant which means my last period was literally 2 weeks after we got home. I am so petrified that at the moment I can't seem to be happy. I can't stop crying. I'm so stressed and anxious everyday to the point I can't sleep, and no one seems to be able to help me. No-one seems to know anything about it. Please, does anyone have any advice or information that they can give to put my mind at ease a bit. All the doctor said to me was 'Just think of all the people that live in those affected countries that have healthy babies all the time" and it didn't help much. Thank you so so much in advance
