Pain in the right lower abdomen in early pregnancy can have a few different causes, and not all of them are dangerous. In many women, mild pain can happen due to normal changes in the body, such as stretching of the ligaments that support the uterus as it begins to grow. Sometimes, the pain may also travel to the leg due to muscle strain or pressure on nearby nerves. However, since you have just tested positive for pregnancy, it is important to be careful because similar pain can also be seen in conditions like an ectopic pregnancy (when the pregnancy develops outside the uterus, usually in the tube) or, less commonly, an ovarian cyst. These conditions need early medical attention. You should not ignore the pain, especially if it is persistent, getting worse, or associated with symptoms like dizziness, shoulder pain, vaginal bleeding, fever, or difficulty walking. It is best to consult your doctor as soon as possible for an examination and an early ultrasound to confirm that the pregnancy is in the correct place and progressing normally. Until then, avoid heavy activity and get adequate rest.
