Congratulations on your pregnancy! I totally understand the worry, especially travelling so early without that first scan to reassure you. Most people do travel in the first trimester and it's generally fine, but honestly at 4 weeks with so much uncertainty, it might be worth having a quick chat with your doctor before you go, just to get their take on your specific situation and what to watch out for while away. Week 9 for your first proper gynae visit is normal enough, though some people prefer to see their gynae earlier just for peace of mind, so that's something you could ask your doctor about too. The first trimester can feel like a waiting game, especially when you're far from home, but try not to overthink it too much. Wishing you a smooth trip and a healthy pregnancy ahead!
