Not that i know of. Think of all the women that eat really hot foods in some of the countries where chillie's and curries are part of the standard diet. They have no problems. There is an old wives tale (could work theoretically i guess) that spicy food induces labour. This works on the theory that anything which irritates the stomach irritates the uterus (possibly causing contractions). I ate spicy food when i was pregnant with my daughter and she came out fine. Eat what you usually do, its unlikely to harm the baby.
