Mirena IUD

Sarrah
Hey, 
 My name is Sarrah i am 20 years old about to turn 21..I have had this app for about 1 year and it is very accurate and I love it! Well I have never been pregnant, and I just had my Mirena IUD inserted yesterday and it hurt like all hell! My question is that, when am I supposed to stop cramping and bleeding badly?! I have missed 2 days of work already and it hurts super bad. When it was inserted yesterday 3/20/17 I was throwing up, having hot flashes, sweating, and shaking..I just want this pain to go away 😢 does anyone have any advice please
  Thank you 😊
