NETA is a potent synthetic progesterone. While our bodies naturally produce progesterone, taking NETA in pill form provides a higher dose that tricks the body into thinking it's pregnant, thus preventing the shedding of the uterine lining. It's effective for various treatments, including addressing menstrual disorders, managing endometriosis, and, notably, for delaying menstruation.

Another synthetic form of progesterone, MPA functions similarly to NETA. It is available both as an injectable contraceptive and in oral form. When taken orally, MPA can effectively regulate menstrual cycles and delay periods by stabilizing the uterine lining.

Commonly referred to as birth control pills, COCs contain a blend of estrogen and progestin. By taking them continuously, without the typical seven-day break or placebo pills, you can effectively delay menstruation.
