The Sayana Press injection contains a high dose of progestogen that stays in the body for 3 months after the injection is given. It contains the same hormone as the Depo-Provera injection
but you can administer Sayana Press yourself. It is really great at stopping periods after a few injections. The downside is that once it's given, it's in for 3 months and cannot be removed or stopped before then if you have side effects and want to stop using it.
