Frequently Asked Questions

Is cramping normal in early pregnancy?

Mild cramping in the first trimester is common and often caused by implantation or the uterus growing. It should feel like mild period cramps, not severe pain.

How do I know if cramping is a miscarriage?

Miscarriage cramping is typically severe and accompanied by heavy bleeding and tissue passing. Any combination of heavy bleeding and cramping needs immediate medical attention.

Can round ligament pain cause cramping?

Yes — round ligament pain can cause sharp, cramp-like pain in the lower abdomen and groin, typically felt when changing positions quickly.

Is it normal to have cramps at 6 weeks pregnant?

Mild cramping at 6 weeks is often normal as the uterus grows. However, any cramping with bleeding should be reported to your provider.
