I wouldn't go pregnant or not. I have been to Bali before and I got sick for 8 months after with a horrid tummy bug.When I was there I was very careful what I ate (did tonnes of research before going) and only drank bottled water. I was even careful not to let shower water go in my mouth. My uncle recently went for his wedding and caught a horrid bug so bad over there that he was in hospital for months and it damaged his heart that he needed a heart transplant. Thankfully he is now out of hospy and making a good recovery.
