Hi and yes, I have been taking Yasmin and find it makes me much more irritable and angry than I even have been before, although not all the time. It comes in waves. I am older (38) than your daughter so I can recognize what is happening in me, but I can imagine it would be so confusing to a younger woman - a teenager. I would recommend trying a more standard bcp for her.
Thank you for your input. What do you call a more standard bcp? She has also had a lot of weight gain and this has caused body image problems. I am also worried that if she goes off this pill and goes onto another one there will be more weight gain.
