At the earliest stages, after confirmation of pregnancy by a test, but before undergoing an ultrasound of the pelvic organs, there is no definite information about the location of pregnancy development. Cutting pain on the right or left in the projection of the uterine appendages may indicate the development of an ectopic, tubal, or pregnancy. Pain in the area of projection of the appendages, as a rule, is supplemented by pain radiating to the anus and lower extremities.
