I am 15 year old. I had my first periods on 9 july 2016. It lasted for 3 days with very less flow. I started my second periods on 25 September and it is still continuing. I was having very heavy flow till yesterday. I had to change pads after every three hours. Today the flow is lesser comparatively. Today I am changing pads after 5-6 hours. I am absolutely tired of changing pads. We have a very important festival from 6th october to 11th october and I badly want my periods to end before that. Please help.
