Buttock pain during pregnancy can be caused by abnormalities in the buttocks (such as hemorrhoids). It can also be referred pain spreading from the lower back to the buttocks. Pregnancy-related buttock pain usually resolves after childbirth, but some women may continue to experience hemorrhoids after giving birth.

As the pregnancy progresses, the frequency of lower abdominal pain increases. At 38 weeks, this pain could indicate labor or other health issues. In such cases, careful monitoring and hospital visits are necessary.
