Ive tried looking around and can't find exactly what I'm looking for. And cant reach my doctor right now. I work as a delivery driver. I'm starting my 18th week if pregnancy and I dont have any a.c. in the car and I live in hot sunny florida. I keep 2 to 3 windows down and drink several bottles of water and a couple slushy like beverages daily. I'm just wondering is the baby okay. the sun uv is the worst. but I stay covered and in shade as much as possible. I dont think there anything wrong with this but has anyone else worked like this where there's limited a.c. and is it safe to even be a delivery driver? does all the sitting hurt anything with the baby?.
