Is it okay to travel 8 hours by car driving by yourself?

April

So my husband has to go to northern Texas to work for the week in 2 weeks. There’s an option for me to come, but I’d be driving about 8 hours by myself. Should I call my doctor and let them know I’ll be traveling 8 hours or more by myself? I’ll be 31 weeks pregnant. I’m low risk and haven’t had any complications other than the normal symptoms. But just want to make sure it’s ultimately safe to be traveling even by car when I have 9 weeks give or take until I’m due.
