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.
Menstrual cramping usually starts after ovulation but it is possible to have the cramping but no period. Usually a young girl will start with period cramps before their first period and it can intensify from there. However as previously mentioned some women do not have menstrual cramping at all.
