Not so happy with this zika mess

Tammy • Me and my DH have been TTC for nearly 4 years now. We have 2 beautiful children already, a boy and a girl, and would love one more addition:-)
I probably shouldn't worry but I am a worry wort anyway. My husband is making a trip to Florida where 26 cases of zika have been reported. He is hitting the areas where most of them are reported from too! Idk what to do like when he gets home. Just tell him no sex for the rest of the pregnancy? We dont and never have used condoms as I have both spermicid allergies and latex allergies and its been proven to transmit through sperm.
