Travelling while pregnant.

First of all want to say thank you to this amazing glow app and the community. I’m so happy to share my thoughts, read your experiences and advices. According to aGlow App I’m pregnant 5weeks and 3 days and I can’t express enough my happiness🤗🐣. 2 months ago I booked my trip to Ukraine. I’m Ukrainian, leaving in Sydney. But after I found out I’m pregnant I’m not sure how comfortable I would be, travelling for such a long hrs(14 hrs). I’m also aware about a letter from a doctor you need to have after 26 weeks of pregnancy or so. My question in following. Can you share you long travel experiences when you were pregnant of 20-26 weeks. Your experiences will help me to make the right delicious. Thank you so much for ur support.
