Can tell me about taking norethisterone for a long time and problems?

Fluid retention: Norethindrone Acetate is a moderate potency progesterone compound. It will suppress bleeding, and is often used to suppress the activity of endometriosis tissue. While it is not labelled as a contraceptive, it is contraceptive in nature if taken daily. Fluid retention is the biggest and most consistent side effect. It may increase libido in some women.
