If you have to travel, stick to trains or flights rather than bumpy roads. Carry your own home-cooked light snacks and bottled water so you don't end up eating unhygienic food outside.
Unless it is extremely urgent, avoid long road trips or bumpy auto rides right now. The first trimester is delicate, so keep your travels to a minimum and rest more.
The general medical consensus is that travel is safe if you don't have complications like bleeding or severe nausea. My gynac specifically told me to avoid any rough roads and take frequent breaks to stretch if traveling by car.
We were planning a trip too, but we decided to wait because I feel so tired and nauseous these days. It is better to ask your doctor before booking any tickets, just to be completely safe.
I traveled during both my pregnancies in the first trimester without issues. Just choose comfort over speed, keep your medicines handy, and don't lift heavy bags at all.
