My wife and I went to KL, Hanoi, Hong Kong & Phuket when she was 20-24 weeks pregnant last year. Health professionals in the UK certainly had no issues with the trip and so long as you follow the same precautions as most would when visiting developing countries (bottled water, properly cooked food), there's no added risk that you'll catch anything.
Before 13 weeks is a different issue I believe...
