Ok onky because I read somewhere you should take a shorter break if you take the pills back to back but it didn't say why
No, you should still have a 7 day break.
If you really, really can't have a 7 day break for whatever reason then you can have a shorter break, but this will increase your chances of breakthrough bleeding (ie bleeding when you're not on your break).
You must not have a longer break unless you realise you're not protected and use additional contraception.
