I was told I couldn't go to Cabo, Mexico in my first trimester because of the Zika virus. They had told me if I did get it they wouldn't even be able to find out til the 3rd trimester. So I just cancelled my whole trip, which was supposed to be our honeymoon. 😩 better safe than sorry!
Our baby moon was supposed to be in P.R. Booked the hotel and plane and everything and decided not to go because of Zika. 😞 You're not supposed to have sex within 6 months of someone going to a Zika infected area because it can be transmitted sexually. I wouldn't risk the first trimester at all.
I think you should be okay if you were there 5 months prior but I wouldn't suggest going during mosquito season.
