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.
These are the same contractions that you will experience when labor begins, but the difference is that they will not progress into labor. Of course, when cramping occurs in the third trimester or even in the second, it's important to determine whether you could be experiencing preterm labor. Shop all pregnancy books.
