Why does right lower abdominal pain occur in biochemical pregnancy?

The main possible causes of right lower abdominal pain after biochemical pregnancy are as follows: 1. Uterine contractions: Although a true gestational sac does not form in a biochemical pregnancy, the degeneration and loss of the fertilized egg can still stimulate the uterus to contract. The uterus is typically dextrorotated (rotated to the right), so uterine contractions may manifest as dull pain in the right lower abdomen. This is a normal condition and the pain can be relieved by methods such as applying heat to the abdomen. 2. Right adnexitis: After a biochemical pregnancy, some women may experience decreased immunity, making them more susceptible to pathogen invasion and infection. If right-sided adnexitis develops, it may present as dull pain in the right lower abdomen. In such cases, anti-infective treatment under medical guidance is necessary, such as taking traditional Chinese medicine like Fuke Qianjin tablets. Right lower abdominal pain following a biochemical pregnancy may be caused by either uterine contractions or right adnexitis. If the pain persists or worsens, prompt medical evaluation is recommended so that a doctor can make an accurate diagnosis and provide appropriate treatment based on the individual situation.
