IUDs are safe for most people with a uterus, and copper toxicity is super rare. That said, it can happen, especially in people with Wilson’s Disease, a rare genetic condition which affects about 1 in every 30,000 to 40,000. Wilson’s Disease affects the body’s ability to process copper. Given how low the daily dose of copper is from the non-hormonal IUD, it is extremely unlikely that someone who does not have Wilson’s Disease would experience copper toxicity. So unless you have Wilson’s Disease, you don’t have to worry about copper toxicity from a copper IUD.

Can the IUD hurt my partner?
No, the IUD won’t hurt your partner even if they can feel the strings. You may have heard that the IUD strings can bother partners who have a penis while having sex, but most partners don’t even feel the strings, and the strings usually soften over time. If your partner can feel the strings and that bothers them, your health care provider can trim them to see if that helps.

What are the best methods to use if I don't want to have my period?
The hormonal IUDs, shot, implant, and progestin-only pill have all been shown to overall reduce periods for most people. For some people, that means they don’t get a period at all, but for others it can cause bleeding when you aren’t expecting it even if you have less total bleeding.
You can use the pill or the ring continuously to intentionally skip your period altogether.
Is there anything that helps with IUD insertion pain?
IUD insertion itself is pretty quick (less than a minute or two for experienced providers), but it’s hard to know exactly how much pain you might have since pain can vary from person to person. Some people experience very little pain, like mild period cramps, and some people experience very intense pain when an IUD is inserted.
You can try taking ibuprofen beforehand, and some providers may recommend getting the IUD inserted when your cervix is open, such as when you’re on your period, but you can have it placed anytime during your cycle. Some providers may be able to use pain medication directly into the cervix and others can put you to sleep while it’s placed. Other techniques like breathing exercises and meditation can also help with pain. Even if there is some pain, it might be worth it for sex without worrying about getting pregnant.

Will birth control make me gain weight?
Most birth control methods will not cause weight gain. Everyone’s body responds to birth control differently, but research shows that the pill, patch, the hormonal IUD, the ring, and non-hormonal birth control methods like a copper IUD or condoms don’t cause weight gain (or loss). Studies do show that about 1 in 4 people who use the shot will gain some weight (around 5% of body weight).
Does birth control cause blood clots?
Using a method of birth control with estrogen, like the pill, patch, or ring, increases the risk of forming a blood clot, but the risk is so low that if you don’t have any factors that increase your chances of having a blood clot, you can safely use all types of birth control. If you do have an increased risk of blood clots because you’ve had one before you’ve had a stroke or heart attack, or you have a medical condition that increases your risk of a blood clot, like high blood pressure, then adding birth control with estrogen to the mix increases your risk too much and it’s not recommended that you use birth control with estrogen in it. But that doesn’t mean there isn’t a birth control method for you!
If you can’t take estrogen, you have quite a few options available to you. First you have the non-hormonal methods, like the copper IUD. You can also use any of the hormonal methods that only contain progestin, not estrogen, like the implant, mini-pill, shot, and hormonal IUDs, like Mirena, Skyla, Liletta, and Kyleena. These don’t increase your risk of blood clots and are all really good at preventing pregnancy.
If you’re worried about blood clots or don’t know if you have risk factors, talk to a health care provider about which birth control methods are options for you.

What are some of the health benefits of IUDs?
The hormonal IUD (Mirena) dramatically reduces blood loss during one’s period, protecting against anemia. It can also reduce menstrual symptoms in women who have fibroids. And, if you’re a woman who can’t use estrogen, both the hormonal IUD and the copper IUD (Paragard) are good options.

Can birth control help with dysmenorrhea?
If you have dysmenorrhea (the medical term for extremely painful periods), hormonal birth control can make a big difference. Options like the combination pill or a hormonal IUD can reduce the level of pain and heaviness of your bleeding, basically making it easier for you to live your life when you have your period. There are a bunch of hormonal methods that can help regulate your periods, decrease bleeding, or even make your period go away completely.

I’m a smoker. What birth control options are best for me?
For most people, the risk of blood clots when using the ring, the patch, or the combined birth control pill (which is the most common type of pill) is low. But smoking increases this risk. If you are over 35 and smoke 15 or more cigarettes a day, the combination pill, patch, and ring are not safe options for you. If you’re over 35 and you smoke less than 15 cigarettes a day, talk to your provider about whether these birth control methods are safe options for you. People who smoke can always use the IUD, the implant, the shot, the mini-pill (progestin-only pill), and any method that is hormone free (like condoms, for example).
What should I do if my birth control changes my mood?
If you feel like your birth control is changing your behavior, it’s time to talk to your health care provider. Everybody responds to birth control differently, and your provider can help you decide whether it’s time to try something else. It might be a matter of switching hormonal methods or deciding whether to avoid hormonal birth control altogether, or you may choose to wait it out since some negative side effects go away with time. The bottom line: If your current method is making you feel blah, don’t settle. There are a lot of methods to choose from and sometimes it can take a few tries to get it right.
Is there anything I can do if my periods are heavier and my cramps are worse since I got my IUD?
If this is the case, you’re probably using a copper IUD (Paragard). Sometimes things get better if you just give it a couple months. You can also take ibuprofen the first few days of your period.

Does hormonal birth control cause depression?
It can be complicated to tell exactly how hormonal birth control affects mood, but you’re the only one who truly knows how you feel. Everyone reacts to birth control differently, so if you feel your birth control might be contributing to depression, talk with your health care provider. Remember, there are a lot of birth control methods out there—you can find the right one for you!
