SO. MUCH. BLOOD.

So this isn't for me but a friend I'm a little concerned for. Her period isn't always heavy and it's normally 4-7 days long, but lately it's been 10+ days long and she's bleeding HEAVILY. Like, she fills up a 24 hr pad in an hour. Is this bad? Normal? Relatable? She's always talking about it, that's how I know about this 😂. Please comment if you can help?
