Travel restrictions?

I’m trying to plan/attend my baby shower with my family that’s about 12 hours away. I hit third trimester in May. I was thinking about traveling by car in April. I have had a healthy twin pregnancy so far with no issues. My husband is not coming with me but I have a friend who will. He doesn’t feel comfortable with me driving that far and wants me to ask the Dr. which I plan on doing.

*I can’t fly because I can’t transport a bunch of gifts unless I mail them
