"i had the paragard iud for 6 months, i chose this particular birth control because it has no horomones! my experience getting the device inserted was smooth.. it didn&#039;t hurt at all, but there was indeed some pressure! i was sore for about 3 days, my periods stayed the same, and everything was normal.. the only thing i would point on though was i kept having a strong cramp in my tail bone and sex was quite uncomfortable! other then that this birth control gave me no other problems."
