Travel during 8 weeks?

My first trip was 9 weeks to Batam. Didn't really do much csuse feel nausea and tired all the time. Waste $$ but the trip was booked before I found out I was pregnant so no choice but to go. 2nd trip was in my 15th week to Europe. Definitely enjoyed myself more cause no nausea and more energy. I guess its how your body is coping with your pregnancy. If 1st trim you no morning sickness or etc, then should be okay? Anything just discuss with your gynae. :)
