I had my period last month on the 12th. Right after my period, my breasts started getting really sore - on the sides near my armits and they seemed to have gone up a size they are so swollen, my normal bras don't fit. Is this normal with PMS? I had sore breasts before but I never noticed a significant size increase - I am pretty small normally 34A but I'm definitely a B and they seem to be drooping LOL. Just curious if anyone else has this and what I can do to relieve the pain? I can't WAIT for my period to come, and I never say that, as I can't deal with this. I have a past history of endo and am being treated with abx for lyme disease - not sure if it's fluid retention from either of these issues. I called the pharmacy about the meds I'm on and they don't cause retention. There's no weight gain on the scale either, though I feel there should be! Thanks for any thoughts.
