hi greeneternaleyes. i just read your post and i to have noticed some breast tenderness recently. i too am not sure if it is the yasmin but i did read a few mention it in some post. i am really questioning wether i should ever go back on this pill after reading everyones thoughts on it. before i was on yasmin i was on the depo shot. i dont remember any side effects from it other than when i stopped it to have a baby it took what seemed forever to get pregnant again. i only started using yasmin because my insurance wouldnt pay for it. all the side effects of pills is why i dont take anything unless absolutly nessecary.
