Anyone travel within 1st trimester? What are the things to take note?

I travelled when I was 2 mths preg with my number 2. I even carried my 19 mths firstborn throughout the trip as she was super clingy towards me. Having said that, I am glad to spend that time with her before my second child came along. Most importantly, you know your health best. Travel only when you feel comfortable and your hub is supportive.
