5 or 7 day break from microgynon pill?

[C1239]

I normally take a 7 day break between packs but I’ve read it’s becoming more common to take a 4 or 5 day break. Does this result in a shorter bleed? What do most people do?

I think no need to have a break at all? The break is for psychological (rather than) medical reasons as I understand it?

I do run a few packs back to back but then I thought it was good to have a break after a few? Nurses have said it’s fine to run 4-5 then have the break then re start?

I've always taken 21 pills, 7 day break. Periods are always about three or four days.

I’ve personally found a shorter causes more issues with bloating and water retention.
