Are cramps normal in early pregnancy?

Pregnancy comes with a whole host of sensations as your body makes room for your baby. For some women, that includes cramping. These cramps can last throughout your entire pregnancy, but how they feel will change with each trimester.

Christine Gerber, MD, an obstetrician and gynecologist at Atlantic Health, shares more about cramps in early pregnancy, what they feel like and when to seek care if you’re concerned.

Why do cramps occur in early pregnancy?

If you are newly pregnant, irregular cramping here and there throughout your first trimester is totally normal. That’s because, as your growing embryo implants and grows in the uterus, the muscle of the uterus responds by cramping. Cramping may be stronger in subsequent pregnancies since you may be feeling more pelvic pressure, especially after the first trimester.

“As the uterus increases in size, you may be feeling sensations you haven’t felt before as more and more stress gets placed on your pelvic muscles and attachments,” says Dr. Gerber.

Hydration can also play a role in early pregnancy cramps, since you need to drink more water when you’re pregnant than you otherwise would. According to Dr. Gerber, it can take your body time to adjust and your uterus may cramp in response to dehydration.

What are implantation cramps?

At the beginning of the first trimester, as the embryo moves from your fallopian tube to implant in the uterine wall, it can cause cramping, which is completely normal. Implantation bleeding, or light spotting (a small amount of pink, brown or rust-colored blood when you wipe), is also normal.

In the first trimester, cramping and bleeding may be linked, especially with implantation bleeding. However, heavy bleeding, including clots or bright-red blood, warrants a call to your doctor, especially if it’s happening alongside painful or intense cramping.

What do early pregnancy cramps feel like?

Fortunately, early pregnancy cramps should not be extremely painful or frequent, and they should feel similar to cramps you may experience while on your period. You may also feel these cramps in a range of locations, which vary depending on your anatomy and how your uterus is growing. For example, you may feel cramping in your back, abdomen or lower in your pelvis.

“Cramps shouldn’t be uncomfortable to the point of you needing to stay home or limit your activities,” says Dr. Gerber. “And you’ll likely feel cramps where you’d feel them with your normal period.”

What is normal for early pregnancy cramping?

While cramping is normal in the first trimester, it should:

Be infrequent and irregular
Improve with rest and hydration
Not keep you out of daily activities
Not require pain medication to ease

“Listen to your body,” says Dr. Gerber. “If you’re tired, rest. If you’re starting to feel a rhythm or regularity to your cramps, they aren’t going away with rest or fluids, or the intensity is increasing, it’s time to call your doctor.”
