If you have vague pain in the right side of your abdomen after pregnancy, it is okay to observe it for a while as long as the pain is not serious, it may be caused by the pregnancy itself. However, if the pain worsens after the activity, it is necessary to pay attention to the possibility of pre-miscarriage. If you have appendicitis before pregnancy, it is recommended to go to the hospital for examination when you have hidden pain, even if the symptoms are not serious, mainly to avoid recurrence of appendicitis, which may lead to miscarriage if it has an acute attack. In case of pain in the right side of the abdomen, it is best to rest in bed. It is not recommended to apply heat or pain medication, because applying heat to the abdomen or applying pain medication on your own may affect the development of the fertilized egg or cause malformations and abnormalities in fetal development.
