A progestin-only contraceptive, also known as the mini-pill, is a form of birth control that contains only progestin hormone and does not have any estrogen. This hormonal contraceptive is taken orally in pill form. It works by thickening the cervical mucus, which makes it difficult for sperm to reach the egg, thereby inhibiting fertilization. Additionally, it may also thin the lining of the uterus, preventing implantation. Progestin-only contraceptives are an alternative for individuals who cannot or prefer not to take estrogen-based contraceptives due to certain health conditions or concerns.
