I am a 16-year-old girl and I have had my period for about five years now. My mom and doctor have both said that I am most likely finished growing, but I am not so sure. For one, I get random growing pains in my legs and arms sometimes, but the last few days I have also noticed some other things growing. My normal bra size is a 36C, but the last couple of days my bras have felt too tight and uncomfortable. Around the time before and during my period, my breasts normally get sore and swell to the point where I have to wear a bigger size bra (38C). The last few days they have felt that way, but my time of the month is still a couple days away. Could it just be early PMS causing the pain and swelling, or are my breasts just growing bigger? Like I said, I was under the impression that everything was finished growing. Thanks in advance for any help!
