I experienced breast sensitivity and enlargement after taking Yasmin for just one month and have stopped taking it as a result. Does anyone know if this is a common side-effect? My doctor prescribed Yasmin to improve my skin and mood swings before my periods, but I can't report any noticeable improvement in this regard. In fact, I still had one or two pimples before my period. Does anyone know if these side-effects would have abated with time if I had carried on taking Yasmin?
