If you’ve ever had to deal with a heavy period flow, you’ll know all too well the nagging fear of leaking through your clothing or onto the bed sheets. Fear not, this handy and simple period tip has been labelled a ‘game changer’ for heavy flow and postpartum bleeding.

The clever tip was shared by Alice Williams, the founder of Ovira (a device that gives instant period pain relief), who has been hailed as some sort of demigoddess for the idea.

The tip is to place a pad like you normally would in your undies, but then get another pad and place that horizontally where your bottom goes. I know right?! The video has been viewed almost 20 million times, with women understandably praising the concept.

“Horizontally is a game changer,” wrote one woman.

“I learn something new on TikTok every single time I come on here. Why didn’t I know this earlier?” wrote another.

“And I will finally be able to sleep on my back and not fear,” replied Eleanor.

“This would have been great for postpartum,” wrote Juliana Jones.

Some women did point out that overnight pads are designed to stop leakage from behind, others said they’re simply not wide enough.

  • Well what a simple and good idea this is!


  • I have ridiculously heavy periods (endometriosis, blood thinners and I’m over weight) so I use u by kotex overnight long pads, I wear one the normal way but back a little further then normal and I add another backwards so the larger part of the pad covers the front. When it is at it’s heaviest I wear period undies over my regular undies with the pads in them just in case I have a leak from the sides, when I am working I can’t get to the toilet at regular times to keep on top of things


  • Just passing this onto my 13 year old daughter!


  • This would have been handy to know as a small child. This is something I’ve been dealing with since I was 9


  • It’s no longer relevant to me anymore but this would have been great to know back then. I would have to use those plastic knickers with my pads to guarantee at least a couple of hours sleep overnight.


  • It seems so logical and what a good idea!!


  • Whilst it’s not relevant to me anymore, I wish I’d known this years ago.


  • This is actually a really good idea, I’ve switched to period undies so don’t feel I need to stress about leakage anymore but this would have been a lifesaver especially during heavy periods at school


  • I find maternity pads are fantastic especially when super heavy.


  • Overnight pads were usually enough for me.


  • Not a bad idea! I haemorrhage when I have my period, but most of the time super, overnight or maternity pads do the trick…
    My little hack to add for pads, is to put them in your child’s underwear when they are potty training. It helps to keep part of the mess contained


  • Never thought of doing that with a heavy flow and sometimes period undies aren’t enough if you flow is THAT heavy.

    • Yes, my daughter leaks through the period undies and uses overnight pads in the period briefs


  • What a brilliant idea! I’ve since switched to period undies because of leaking, but will remember this!


  • Genius. Wish I would have thought of doing this.


  • I have used modibodi period knickers for a few years now and they are fantastic. I have to use the heavy overnight ones but a lot better that having leaks all the time. My teenage daughter wears them all the time. She likes to feel safe even when she doesn’t have her periods.
