Yeah my only concern would be morning sickness. I literally cannot move or do anything when I have MS so I would make sure you keep tours/plans to a minimum in case you just want to lounge around the pool sipping mocktails.

Your body is designed to protect your baby. They will be just as safe in your belly in Bali as in Australia. Normal food guidelines for Bali would apply: avoid pre prepared fruit and salad and drink bottled water etc. the hardest thing will be avoiding icy cold beer when you're down on the beach!

Have fun!
