So ive noticed that my left nipple os more tender then my right? But they both are. Usually with my breast tenderness its been the whole breast but this time is just the nipple. Should i be worried? Ive been taking microgeatin fe 1/20 for 4 months now ive never evee missed a pill ive taken them on time and i was just worried... i mean my appetite has gone up, but i have been working out more and now the tender nipples. Can someone please explain to me whats going on and my protection on microgestin?
