After turning 29 for more than 1 birthday I experienced this. 32 day cycles, 3 days and done, no complaints here!
Yeah, I thought it was just my getting older. I'm 33, and I thought that explained the shorter periods. I'm absolutely regular and my periods are 2-3 days. But Katrina is 28 and has, until recently, had quite long periods. The change for her is what made me start to think that maybe veganism played a role for both of us.
I went off birth control about the same time as vegan....so I'm not sure which caused it, but they are way shorter than they used to be! On the flip side, I NEVER used to get cramps, and I do sometimes now - and that sucks.
I have always had pretty horrible cramps with my period, and that hasn't changed. I just get them for a shorter period of time!
