Actually since 2 months I am getting my periods on time but the flow is much less than before. Like before 2months I usually bleed heavy in 1st n 2nd day then from 3rd day it decreases, but in these 2months I have observed that it is decreasing from the 2nd day itself. I have changed my location for job purpose it's like I used to stay towards east in Odisha and now since 2mnths I have shifted to Bangalore so just want to know that why is this change happening.
