I am about 4 weeks pregnant and leave to Guatemala for vacation. I will travel by bus (bumpy bus rides), sleep in backpackers hotels, carry my backpack around, and visit dusty local markets. I wanted to do adventurous things (tubing, caving, snorkeling, horseriding etc), but I guess I d better skip that. Would you have any other advice for me? Are bumpy busrides dangerous? Sleeping at midrange hotels (small chance on bedbugs)? Pressure on my belly from the strap of my backpack? Your guidance will be appreciated.
