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?
