This 25 year old woman has never given birth and has no history of STIs. Each photo was taken at approximately 10:00 pm every day starting the first day of her menstrual cycle. For the duration of this project, she used condoms as her birth control method so as not to introduce semenal fluid into the photoshoot. She did not use tampons or mooncups during her menstruation either.
If you've never see a cervix before, now's the time! Be warned, these are real internal body pictures and some do include blood as they illustrate her menstrual cycle.
