"Literally the only good thing Kariva did was prevent pregnancy and clear up my acne. I&#039;m 18 and it&#039;s the first birth control I&#039;ve ever tried. Within the second week of taking it I had a lower sex drive, I gained weight and I couldn&#039;t get wet no matter WHAT I did. Also, my periods were never bad to begin with, but on this pill they were SO heavy for 7 days. I had extreme cramping, was always tired, and had shooting pain through my anus every time I would sit down on the toilet. I&#039;ve been off this for 3 weeks now and everything is completely back to normal."
