"when i first got it it would do what i would call &quot;resetting itself&quot;. by that i mean about every 3 months i&#039;d have a week or two of insane pregnancy symptoms and it was awful but they would go away. i no longer have that happen and i love that it makes my periods super light. it gives me such security and is very effective. the pregnancy symptoms sucked but they only lasted a week or two, compared to 18 years of not  having a child i&#039;d say that&#039;s ok. it&#039;s painless to get in and is amazing."
