This means you only experience a bleed once every three months.

Sources- PMID 42701530 Katie on TT During an abdominal ultrasound, sound waves must travel through several layers of skin, muscle, and tissue before reaching the pelvic organs. To cover this distance, the scanner uses lower-frequency sound waves, which penetrate deeper into the body but naturally create a softer, less detailed image. An internal ultrasound provides a much clearer view simply because it places the small probe closer to the area being examined.
