Here is a leave letter you can give to your class teacher:
Date: 4th August 2026
To,
The Class Teacher,
[Your Class & Section]
[School Name]
Subject: Leave Application Due to Severe Menstrual Health Issue
Respected Ma'am/Sir,
I am writing to inform you that I am unable to attend school today as I am experiencing a severe menstrual episode since yesterday morning. I have been having very heavy bleeding with tissue/skin-like discharge, which has caused significant discomfort and soaked through my clothing and bedding overnight.
I am also experiencing dizziness, extreme fatigue, and lower back pain, which are making it very difficult for me to sit, stand, or concentrate. Given the severity of my condition, my parents/guardians feel it is best that I rest at home and consult a doctor.
I kindly request you to grant me leave for [number of days, e.g., 1-2 days] and excuse my absence from classes and any assignments due during this period. I will make up for any missed work as soon as I recover.
Thanking you for your understanding and support.
Yours sincerely,
[Your Full Name]
Class: [Your Class & Section]
Roll No.: [Your Roll Number]
Date: 4th August 2026
Health Note: Heavy bleeding with tissue-like clots, dizziness, fatigue, and soaking through pads/bedding (flooding) can be signs of conditions like menorrhagia (heavy menstrual bleeding) or other concerns. Please do see a doctor soon - especially if the bleeding is very heavy or you feel faint. Take care of yourself.
