I did not expect this. I expected conversation about dwindling sex drive and all that nuts and bolts stuff.
To answer your question though, I think that women who are really emotional during periods are the ones who have issues at menopause. It never affected me the way you are describing. Sorry.
One more thing, your hormones might be normal, but what if you have some other problem with your uterus that causes the cramping and bleeding?
When I was right about your age, periods got nasty but it lasted less than a year. hang in there. On the other side, it is awesome.
