Progestin-only pills, or mini-pills, are often prescribed to help women manage heavy periods, especially when a woman is looking for contraception when breastfeeding, has problems with estrogen-based contraceptives, or is at a heightened risk of blood clots.
How Do Progestin-only Pills Work to Regulate Periods?
Progestin-only pills, like Camila and Norethindrone, help to regulate your cycle by controlling ovulation and the thickening of the endometrial lining. They also increase cervical mucus, making it more difficult for sperm to reach and fertilize an egg. Most women who take progestin will often see lighter periods, a reduction in severe premenstrual symptoms, and more regular cycles. In some cases, some women may completely eliminate their period while using progestin-only pills.
These effects are often attributed to the fact that progestin, will cause the endometrial lining to be thinner so that it cannot sufficiently support an embryo. Thinning lining often means less cramping to expel it and also less bleeding, as there is less lining to shed.
