Should I go back on pill again (yasmin)?

I'd say that's a personal decision. If you like the way your skin looks while taking it, continue taking it. You might even want to look into a pill like the new Seasonique. You only have 4 periods a year (if that is something you're interested in) and it helps the appearance of your skin, makes PMS less drastic ect. It is entirely up to you. Of course you have to factor in the cost as well. Good luck.
