You should be fine. Maybe just get clearance from your doctor. I would bring medical records with me just in case.
If you're worried about the traveling aspect - no, you are fine so long as you are not high risk or in need of special assistance. You can fly or drive until sometime in the 3rd trimester, different doctors suggest different dates, but 2nd is fine. I've traveled by vehicle & flight internationally & cross country while pregnant. We are a-okay.
