Some women are very sensitive to hormonal forms of birth control. They cannot take pills or even have a hormone-releasing IUD without having side effects, like headaches, mood changes, bloating, or weight gain. These people might get by with natural family planning or using barrier methods, but if you are sensitive to hormones, you might also ask your gynecologist about getting a copper IUD. Here's what you should know about this form of birth control. 

How does it work?

Copper IUDs are highly effective forms of birth control. They work by releasing a low level of copper ions into the uterine space, which are toxic to sperm. The copper also irritates the uterine lining, which makes less hospitable to implantation. Finally, the shape of the IUD helps to prevent the travel of sperm through the uterus and into the Fallopian tube, preventing that sperm from fertilizing the egg traveling down. 

After the IUD is placed, it is immediately effective. It is also easy to recover from if you want to have more children in the future. Once the IUD is removed, you can get pregnant that same day because you don't have to wait for hormones to wear off or for your reproductive system to recover. 

How long does it last?

Copper IUDs are one of the most cost-effective because they are the longest-lasting form of birth control. One IUD can last up to 10 years. Hormone IUDs usually offer about half that time, and pills and shots offer coverage in weeks and months. You don't have to take any medication or worry about missing a dose with an IUD. You can have it placed and then forget about it. 

Are there any side effects?

Like all types of birth control, there can be some side effects. The most common side effect with a copper IUD is heavier bleeding and more intense cramping during your menstrual period. Your period might be longer or irregular on the copper IUD. Therefore, if you already bleed heavily and have bad physical reactions to menstruation, the copper IUD might not be the right type of birth control for you. However, some people find that as they continue with the IUD over a period of a few years, the cramping and bleeding become less severe.
