PERIODS ARE THE WORST

Jasmine
Hey guys, I recently got my first period and I need help! It's been 8 days and still hasn't stopped! It started off moderate and each day has gotten increasingly heavy, especially today it was so heavy I constantly needed to change pads and wash off. I've been getting lots of cramps and really bad migraines. I've also felt nauseous, gotten some back aches, and so light headed I felt like I was going to pass out! Although I've been taking medicine it doesn't seem to have helped much! I'm 15 and pretty skinny, making me not understand why this period is never ending and so heavy! I don't know what to do and my mom recommended I go see a doctor if it hasn't stopped by tomorrow. Please help!!!
