I'am almost 15 and my right breast is almost a cup size bigger than my left. First saw them growing at different rates at around 12. I definitely feel a little more pain on the right one during or before period and occasionally there is this pinkish patch on the far right on it. My left has a normal breast and feel to it but my right one is starting to worry me. I've scheduled a ultrasound in 2 weeks anybody went through anything similar or has any advice?? Thank you!
