🩸The uterus grows a thick inner lining called the endometrium to support embryo development.
🔥If pregnancy doesn't occur, the uterus constricts its blood vessels, depriving the endometrium of blood and oxygen.
💥The uterus contracts to shake off the endometrium, causing it to be expelled through the vaginal canal.
😖The constriction of blood vessels and uterine contractions can result in painful period cramps.
⌛️A period typically lasts around three to five days, but the duration can vary for each individual.
