Birth Control
"Horrible!!! Omg i bled for the first 4months nonstop! My iron got so low i was put on iron tablets and had to change my diet! 

Ive put on almost 5kg since having it in for 7months even though i go to the gym up to 5 days a week and eat very very healthy.

Insertion was worse than childbirth and side effects like daily headaches and migraines, massive mood swings, feeling really angry and then sad."
