The vague pain in the right side of the small abdomen during pregnancy cannot be said to be a sign of ectopic pregnancy, which can also occur under normal circumstances or with gynecological inflammatory infections. In case of ectopic pregnancy, irregular vaginal bleeding will occur, and the pain will be mild in the early stage, but will become more intense as time goes by. If there is a vague pain that does not increase with time, this should be a normal sign. This is because during pregnancy, the enlargement of the uterus can also be implicated in causing painful sensations. Usually, you should pay attention to bed rest and not to exercise strenuously, and this situation will slowly improve or be alleviated, if it is an ectopic pregnancy. In case of ectopic pregnancy, if the pain in the stomach is severe, you should have a timely checkup to determine the condition and then take symptomatic treatment.
