Abigayle • I want a strong and healthy body
Hey I am 15 and I have really bad cramp on my first and second day of my period and it makes me feel like poop. During the school year I had to ask my mom if I can miss school for 2 days and I am in High School now so it's like important to be at school. Should I go on Birth Control to help reduce to cramps even if I am not sexually active and won't be for a while.
