My problem is that mine is so irregular, that I honestly don't have any idea if, when (early/late), how heavy/light, or for how long (3-11 days) it will be "visiting". The bigger problem is that i don't know how to add/edit/show on my glow calendar 2 days medium, 1 day off, 2 days light, 2 days off, 3 days medium, 1 day very light. .. - http://glowing.com/community/topic/8241?utm_source=android&utm_medium=shared_to_third_party&utm_campaign=glow_community
