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.
The first trimester of pregnancy lasts for about the first three months of pregnancy, and is usually the time when a woman realizes that she is pregnant. During the first trimester a woman may experience nausea, extreme tiredness, headaches, mood swings, and several other symptoms.
