eli5: Period is active bleeding?

644 views

Okay so I learned back in 3rd grade or whatever that all month long, your body was building up blood and tissue in your uterus to hopefully implant an egg and get pregnant. When that fails to happen, you shed that blood and tissue.

In my mind, that stuff is kinda “ on the shelf”, yeah, it’s blood and tissue, but not like ACTIVE blood pumping through your heart, right?

So why, when I’m having my period, do people say, “ you’re losing a lot of blood, take it easy”. I thought all that blood has been siphoned off all month, and it shouldn’t make a difference? I mean, it’s not like I need a tourniquet for an artery- even if it’s obnoxiously heavy sometimes.

Is it built up all month?

Or like an active wound?

I’m a 40 year old woman who should know this shit. Help.

It is not like an open wound. It’s not something you could cauterize and ‘stop’. Your uterus builds up a nice, cosy lining for a potential fertilized egg, and when that egg exits, so does the lining. Its more like the lining is a celebrity entourage, and the egg is the celebrity. They all gather around it, and leave when it does…..
