You may feel a tightness of the abdomen, accompanied by slight pain or shortness of breath. The main thing to remember with Braxton Hicks contractions is there should be no progression of symptoms — they shouldn't worsen or occur more frequently. But remember that they can become a bit more intense as you approach your due date. Braxton Hicks contractions can cause a little discomfort, but they’re a completely normal part of pregnancy. They play a key role in helping your body prepare for the big day when you actually go into labor.
