There is no data to support this, so don’t force yourself to eat something spicy if you don’t want to!
Many women swear by spicy Chinese food as the thing that finally put them into labor. The truth is that there are no studies to confirm or deny this. Therefore, only eat these foods if you want to (and can stand the heartburn you might get!).
If you are having some contractions and think you might be in early labor, keep in mind that a belly full of spicy peppers might not taste so good on the way up. You may want to reach for something more bland instead.
