"I don't recommend this birth control to anyone.  Ever since I got it in, it has been a non-stop emotional roller coaster, my mood swings are out of control. Also no sex drive, no energy and weight gain.  But the worst part is I tend to have 2 or more periods in a month. Started my period,  after 7 days it stopped, two days later I am bleeding heavy again,  was on my period for another 9 days.  One time I heavily bled for 20 days straight. I'm getting this taken out."
