Hi Hopeful,
There is no evidence to suggest taking a pill continuously causes any harm at all with regards to not having a bleed so don't be worried about that.
i have never tried Yasmin but it does get some good feedback as it's one of the newer pills and some women find that it helps with symptoms. Personally I tried a few cocs and reacted to them all but everyone is different. My preferred route was the GnRH analogues and I was very well on them (after they licked in and I got HRT sorted out).
Nick Panay recommends Yasmin here (Ctrl F to find it on the page)
