The same rules apply for pedicures as manicures. Bring your own instruments (nail file, cuticle clipper, etc.) from home to reduce infection risk. Steer clear of salons with a particularly strong chemical odor -- look for those with air-conditioning or fans so you don't inhale fumes. If you do your nails at home, apply polish in a well-ventilated area (near an open window) for the same reason. Also, say no to foot massages, which can stimulate fetal activity and contractions.
