Pregnant mothers experience abdominal cramping as a normal sign during the first trimester of pregnancy but this can be otherwise a signal of an underlying problem. If cramps become intense and accompanied by severe bleeding and pain, or if one thinks she is not pregnant, consult a doctor immediately.
Early contractions. You can experience contractions even in the first trimester as your body adjusts to the pregnancy. The stretching of the ligaments around the uterus can cause contractions, as can dehydration, constipation and gas pains. If they're accompanied by spotting, bleeding and/or abdominal pain, you need to see a doc to rule out an ectopic pregnancy or a potential miscarriage.
