Serious causes of cramping include urinary tract infections (UTIs), ectopic pregnancy, miscarriage, preeclampsia, preterm labor, and placental abruption.

The second trimester of pregnancy is weeks 13 through 26, when the baby continues to grow and develop rapidly and the mother will notice a number of changes. 

Common causes of cramping during pregnancy may include:

  • Round ligament pain
    • The round ligament supports the uterus
    • When the uterus expands, it causes the round ligament to stretch
  • False labor (Braxton-Hicks contractions) 
    • Cramps can occur at irregular intervals in preparation for childbirth
  • Gas/bloating
  • Constipation
  • Sexual intercourse/orgasm

Serious causes of cramping during pregnancy include: 

  • Urinary tract infections (UTIs)
  • Ectopic pregnancy 
    • Is usually a problem earlier in pregnancy
    • A fertilized egg implants outside a uterus
    • This causes painful cramps
    • It is a serious condition that must be treated
  • Miscarriage
    • Cramping may range in severity from mild to sharp and be accompanied by vaginal spotting
    • Contact your doctor right away if you experience severe cramps and/or heavy bleeding
  • Preeclampsia
    • A serious complication of pregnancy in which high blood pressure (hypertension), protein in the urine, and evidence of organ injury develops in a pregnant woman after 20 weeks of pregnancy
    • Can cause pain and cramping in the upper abdomen
  • Preterm labor
    • If cramping occurs prior to 37 weeks gestation it may be a sign of preterm labor
  • Placental abruption
    • Occurs when the placenta separates from the uterus before the baby is born
    • Cramping is painful and does not go away
    • This is a potentially life-threatening condition
    • Contact your doctor right away if this occurs
