birth control
"When I first got it it would do what I would call "resetting itself". By that I mean about every 3 months I'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'd say that's ok. It's painless to get in and is amazing."
