I'm on Cerazette, mini-pill, which you can take within a 12 hour timescale, ie, if you forget it at your normal time of taking it, you have up to 12 hours to take it without jeapordising your protection.
Overnight, it stpped my PMT, I have no periods (bliss) and my skin is lovely (after regular outbursts). It's been a real life changer for me.
