I started my period over a week ago but it was just light spotting with cramps off and on,..then finaly a couple of days ago, the cramps got a little heavier and I started what seems to be a normal flow. My breasts have been swollen and tender through out the whole process and havn't let up at all. Is that normal for homornal disfunction? I'm 30, so I don't know if your body can change that much. Anyone out there with a similar experience?
