В ожидании первенца

not pregnant related but.. please help!

I need to get onto the freeway! I have my license and have had it for almost 3 years. I'm terrified of getting onto the freeway and I'm really wanting to get comfortable before I get a big belly (I'm only 14 weeks). I'm a good driver, I drive everywhere in town. Do you ladies have any advice that can help me get over this fear because I want to be able to drive my baby around and not be nervous about it..
