I used to set two alarms a night just to change my pad
Quick answer: Overnight leaks on heavy flow usually happen because a daytime pad is being worn past its rated hours, or because coverage doesn't extend far enough at the back. Use a pad specifically rated for overnight wear (7–8 hours), with wide coverage at the back and sides — not just a bigger version of a daytime pad.
For years, my night-time routine on a heavy flow week looked like this: alarm at 2am, tiptoe to the bathroom in the dark, change, get back into bed, set another alarm for 5am, do it again. Some nights I'd skip the alarm and just... not sleep properly, half-listening for that warm, sinking feeling that meant I'd left it too long.
If you've ever done this, you already know the tiredness isn't really about the blood. It's about the vigilance. You're not sleeping — you're on watch.
It's more common than the silence around it suggests
Heavy periods (what's medically called menorrhagia) affect a large number of women at some point, but you'd never know it from how rarely anyone talks about the practical, 2am reality of it. Most of the conversation stays clinical — "see your GP if flow soaks a pad every hour" — which is useful, but it skips the part where you're lying awake doing mental maths about how many hours of sleep you can risk before you need to check.
I spent years assuming this was just what heavy periods meant. Bad sleep, ruined sheets, a low hum of anxiety every night for a week a month. It took a long time to realise the products I was using simply weren't built for what my body was actually doing.
What actually changes it
Two things made the difference for me, and neither of them was "just deal with it":
Knowing your actual flow, not the flow you've been told is normal. A lot of us were never taught what heavy actually means in hours-and-millilitres terms — we just compared ourselves to friends and assumed we were fine, or assumed we were broken. Neither is usually true. Understanding your own pattern is the first step to actually solving for it instead of just coping with it.
Using something designed for overnight heavy flow specifically, not a regular pad stretched past its limit. This sounds obvious written down, but most of us default to whatever's cheapest or most available, not what's actually rated for the volume and the hours we need it to last. A pad built for heavy overnight flow — the kind with the coverage and absorbency to genuinely get you through 7-8 hours — is a different category of product to a daytime pad, and once I switched, the difference wasn't subtle. I stopped setting the second alarm. Eventually I stopped setting the first one too.
If this is you
You're not high-maintenance for needing more protection than the average pack promises. You're not overreacting by feeling exhausted every heavy-flow week. Your body isn't wrong — the products just might not be matched to it yet.
If you're currently doing the 2am-alarm routine, it's worth actually trying an overnight-specific heavy flow pad before assuming this is permanent. It might not fix everything, but for a lot of us, it fixes more than we expected.
