Getting started

Your perfect period plan

Choose how often you need Semaine based on how often you get your period: 4 weeks? 5 weeks? 8 weeks? You choose on the shop page.

Semaine ships to you each period without you having to lift a finger. We’ll send you a reminder email before we ship in case you need to rush or skip your order.

Open your bottle of Semaine 1-2 days before your period starts (or when you start cramping). Take 2 pills up to 3 times a day as needed.
