We’ve all been that woman. Quickly sneaking away to the bathroom on a busy afternoon, locking the stall door, unbuttoning the blue jeans—only to meet the inevitable stain.  A four letter word finds its way to the tip of the tongue. It has arrived.

Starting today, Android users will have yet another way to remember that the crimson wave is on its way. Glow and Google have partnered to provide helpful card reminders in your Google app, so that you’re alerted to your upcoming period days before it happens.  Now cards will also pop up in anticipation of your ovulation window, keeping you fully aware of when it starts and ends. The Glow app does this, but now Google will do it, too.  Glow is Google’s first period tracker partner—and we think the new cards are way cool.

No more awkwardly asking your friend for an extra tampon. No more emergency runs to the pharmacy. No more artfully folding toilet paper into a makeshift pad that you *hope* will last through the hour. Glow: 2. Period: 0.
