First W30...Early Period

[robynrs]

I'm 47 and am on Day 23 of Whole30.  About 10 days in I started a heavy period (and bright red) 2 weeks early (normally within 1-2 days of 28 monthly) that is still going on 2 weeks later.  I don't know if it's perimenopausal or Whole30 related but the timing seems to point to the diet change.  I've had no other symptoms like pain, etc.  I was supposed to start my regular period 2 days ago so who knows where I am in my cycle. I do have an appointment with my GYN on Monday to discuss, but it is a bit worrisome...
