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

Well, it should be quite safe as many travel without much issues. Although miscarriages do happen usually in the 1st trimester but flying doesn't increase your chance of miscarriage. Let your medical caregiver know you'll be traveling. If you're experiencing early symptoms of what you suspect may be a loss, you might consider postponing your travel if it is possible. Dealing with a loss away from home can be more difficult physically and emotionally. Do note that at least 75% women go on to deliver their babies at term. You may want to choose a seat where you will be the most comfortable, likely an aisle seat so you can access the restroom easily if you need to. I also recommend getting up a little more than normal to walk around and stretch your legs. As mentioned you also really need to carry your own snacks and be sure to stay hydrated!
