We are not medical professionals, but for information purposes, here is a brief overview of the pelvic anatomy of menstruating people.
The vagina is made up of 2 parts: the vaginal canal and the vaginal fornix. The vaginal fornix is located at the top of the vaginal canal and around the cervix.
The vagina is a flattened, elastic muscular tube that conforms to the shape of what’s inside. Although its inner walls are insensitive, its deeper layer is made up of muscle tissue and nerves, which makes the vagina very sensitive to pressure. This explains why it is possible to wear a menstrual disc without feeling anything, but experience many sensations during sexual intercourse.
The inner wall (vaginal mucosa) is lined with bacterial flora that can also be called vaginal microbiota. This microbiota protects against bad bacteria and infections, but to maintain its balance and prevent the proliferation of pathogenic bacteria, the vagina must remain moist and maintain a pH between 3.8 and 4.5. To regulate itself, mucus is secreted by the glands located in the cervix and at the entrance to the vagina. The vaginal mucosa is very permeable and can absorb drugs, but also toxic products with which it comes into contact.
Behind the vaginal canal are the rectum and the anal sphincter.
At the front of the vaginal canal, below the bladder, are the urethra and the internal and external structures of the urethral sphincter.
The muscles of the perineum extend from the pubic bone to the coccyx. These are the muscles that are used to contract the vagina.
At the top of the vagina is the uterus, a moving organ in the abdomen, made up of 3 layers: the inner layer (the endometrium), the smooth muscle, and the outer layer. To prepare for the implantation of a fertilized egg, the endometrium thickens and swells with blood. If the egg is not fertilized, this layer will come off and menstrual fluids will leak out through the cervix.
Since the cervix is often very tender, pressing or stretching its walls can lead to pain. This sensitivity is often the cause of the cramps felt at the start of menstruation. The first menstrual tissues that pass through the cervix stretch its inner walls. Once the cervix is fully open, this type of cramp disappears. Heat helps dilate the cervix. Note that the walls of the vagina and the cervix are the same, so it is impossible for an internal menstrual product to travel anywhere but in the vagina.
At the entrance to the vagina is the clitoris, which is made up of a glans as well as the corpora cavernosa and spongiosum.
During sexual arousal, the labia, the clitoris, the urethral sponge (located around the urethra) and the perineal sponge (located between the vagina and the anus) fill with blood and swell. The smooth muscles of the uterus contract and pull on the round ligaments which tense and pull the uterus and its

The human body is much more complex, but this sums up the basics of the pelvic anatomy of menstruating people.
