When you’re pregnant, your body undergoes many changes as it makes room for your little one (or two or more!). While some of these changes may be no big whoop, others, particularly things like cramping and pain, can have you quickly searching Google for their causes.
While some pregnancy cramps are a normal, others can be a sign of a more serious problem so it's important to know when to be concerned. Pregnancy cramps can give many women anxiety, so it’s important to know the common reasons for their occurrence and what you should do about them.
We asked Bailey Bylow, an OBGYN nurse practitioner with Banner Health, to help explain the normal causes for abdominal cramping, abnormal causes and treatment recommendations for both.
[However, if you’re experiencing severe cramping with or without bleeding, stop reading this article and call your doctor immediately.]
What do pregnancy cramps feel like?
Pregnancy cramps often feel similar to mild menstrual cramps, including a pulling, stretching or aching sensation in the lower abdomen.
What is normal cramping during pregnancy?
Cramping can vary by trimester, with early pregnancy often involving implantation and uterine changes, and later pregnancy including stretching and Braxton Hicks contractions.
Cramping during early pregnancy is common. “Early on in your pregnancy, it’s natural to feel some mild cramping in your lower abdomen at infrequent times as your body prepares for your growing baby,” Bylow said.
As your belly grows, so does your uterus. This may cause you to feel some slight pulling, tugging or stretching similar to period or menstrual cramps.
“Later in your pregnancy, you may experience some mild lower abdominal discomfort due to the tightening of your uterus. These are normal as long as they occur in irregular intervals and subside on their own,” Bylow said. “A common cause later in pregnancy is due to round ligament pain, a muscle that supports the uterus. As it stretches, it can cause some mild aches and pains.”
Other causes for mild cramping include:
- Implantation bleeding
- Gas, bloating and constipation
- Sex
- Exercise
- Braxton Hicks contractions
How to relieve mild cramping during pregnancy
Time your cramps to see how regular they are and how often you feel them. “As long as they don’t fall into the abnormal category, there are some things that you can do to make them better,” Bylow said. Some of these activities include:
- Rest: Try to sit, lie down or change positions.
- Soak in the tub: Take a warm soak in the tub or a warm shower.
- Take some acetaminophen: Products like Tylenol are commonly used by pregnant women for pain and fever but talk to your health care provider first.
- Practice deep breathing: Use relaxation techniques such as meditation, yoga or controlled breathing.
- Stay hydrated: Pregnant women need 50 percent more water. Keep a bottle of water on hand wherever you go.
What causes concerning pregnancy cramps?
While it is common to experience cramping, there are some serious causes of abdominal pain you shouldn’t ignore.
“Any cramping that is severe in intensity, occurs at regular intervals and progressively gets worse with time is abnormal,” Bylow said. “In addition, any amount of cramping associated with sharp pain, vaginal bleeding, increased/watery vaginal discharge, or pelvic pressure is not normal either.”
Serious causes of pregnancy cramps may include:
- Ectopic pregnancy
- Miscarriage
- Preeclampsia
- Bladder infection or urinary tract infection
- Placental abruption
When should you call your doctor?
It’s normal to experience some mild cramping during pregnancy, but always speak with your health care provider if you are ever concerned or are experiencing the above warning symptoms.
“In some cases, an ultrasound can be done to help determine the cause for severe cramping,” Bylow said. “Sometimes severe cramping can be the first sign of miscarriage or an ectopic pregnancy. Other times, it could be non-pregnancy related issues like a bladder infection or constipation which are quite common in pregnancy.”
When it comes to your health and the health of your baby, it’s better to err on the side of caution and talk to your health care provider.
