You are in the middle of an intimate moment, and suddenly you feel a shift—a tiny, terrifying absence where something should be. Your heart stops, not because of pleasure, but because of the sudden, cold realization that your body has just swallowed its own protection.

Let’s be real about this. The scenario we’re talking about isn’t exactly a romantic subplot from a movie. It’s a specific, visceral panic that only happens when you least expect it. You might be moving with someone you trust, or even alone, exploring your own rhythm, and then you feel it. A change in pressure. A loss of resistance. Or perhaps you hear a faint, metallic click, or simply notice that the strings you’ve been checking for months are gone. For a split second, your brain tries to rationalize it. Maybe the strings just retracted into the cervix. Maybe you pulled them too hard last time and they’re tucked away high up, harmless and hidden. But deep down, in that primal part of your nervous system that knows how to survive predators and pain, you know the truth. The IUD is no longer there. And right now, inside you, it might be wandering.

I want you to take a breath with me right now. In through the nose, out through the mouth. Because if this is happening to you today, or if you’re terrified it might, I need you to hear this first: Your body isn’t broken; it’s evolving, and sometimes things move in ways we don’t predict. This is not a failure on your part. This is not a sign that you did something wrong. It is a mechanical event in a biological system, and while it feels catastrophic, it is manageable. We are going to walk through exactly what is likely happening, why it happens, and most importantly, what you do next without losing your mind. Let’s strip away the shame and the fear-mongering stories you might find online. We are going to look at this with clear, pragmatic eyes.

First, let’s talk about the mechanics, because understanding the 'how' reduces the 'what if.' An IUD sits in the uterus, which is a pear-shaped organ. The strings, those little threads you check during your period, hang down through the cervix into the vagina. Sometimes, especially after childbirth or if the uterus is particularly anteverted—meaning it tilts forward—the strings can get tucked behind the cervix. This is called string retraction. It’s annoying, yes. It makes self-checks harder. But it is not the same as expulsion or perforation. If the device is still sitting nicely in the uterine cavity, just hiding its strings, you are still protected against pregnancy. You are safe. The panic here is real, but the danger is low.

However, there is another possibility that causes that specific spike in adrenaline: migration. This is when the IUD moves partially or fully out of place. It can slip down toward the cervix, or in rare cases, push through the wall of the uterus. This is what people often call 'perforation,' though technically, if it stays within the abdominal cavity, it hasn't necessarily pierced an organ yet. It’s just loose. Why does this happen? Usually, it’s because the IUD was inserted incorrectly, or because the uterus is changing shape due to hormonal shifts, fibroids, or simply the natural elasticity of tissue over time. Intercourse itself rarely causes the IUD to disappear unless it was already in a precarious position. So, please, do not blame yourself for having sex. Do not blame your partner. Blame physics and biology, which are indifferent to our intentions.

So, how do you tell the difference between a simple string retraction and a migrated device? Symptoms are your best guide, but they can be tricky because they overlap with normal cycle changes. If the IUD has moved, you might feel cramping that feels different from your usual period cramps. It might be sharper, more localized, or persistent. Some women report pain during intercourse, not in the emotional sense, but a physical deep ache when certain positions engage the cervix or uterus. Others feel nothing at all. That silence is the most frightening part. You can have a completely asymptomatic migration, meaning the device is floating around in your pelvic cavity, doing no immediate damage, but also offering zero contraceptive protection.

This is why you cannot rely on feeling. You cannot rely on hope. You have to rely on evidence. If you cannot find the strings, or if they seem unusually long or short compared to last month, or if you have any new pain, bleeding, or unusual discharge, you need to assume the IUD is displaced until proven otherwise. Do not wait for a crisis. Do not wait for a fever or severe pain to seek help. Act on the uncertainty. Think of it like a smoke alarm. You don’t wait for the house to burn down to check the batteries. You check them the moment you hear the chirp. In this case, the chirp is the missing string. It’s your body’s way of saying, 'Hey, check the dashboard.'

Okay, so you’ve noticed the issue. What is the very next step? This is where pragmatism saves the day. First, stop using the IUD for contraception immediately. Assume you are fertile. Use condoms or abstain. Do not gamble with your peace of mind. Second, make an appointment with your provider. Not your GP if you can avoid it, but whoever placed the IUD or a gynecologist who specializes in reproductive health. Tell them exactly what happened. Say, 'I believe my IUD has migrated or expelled.' They will likely order an ultrasound. This is the gold standard. It’s non-invasive, quick, and it gives you a map. X-rays can also be used if an ultrasound is inconclusive, as the IUD contains metal that shows up clearly.

While you wait for the appointment, monitor your body. Keep a log of any pain, bleeding, or temperature changes. If you develop a fever, chills, or severe abdominal pain, go to the emergency room. These could be signs of infection or perforation of a nearby organ, though these are rare. Most migrations are caught early and resolved easily. The goal is to locate the device and remove it safely. If it’s still in the uterus, they might be able to retrieve it with a simple instrument during an office visit. If it has moved into the abdominal cavity, a minor surgical procedure called laparoscopy might be needed. It sounds scary, but it’s routine. It’s keyhole surgery. It’s fast. And it’s necessary because a loose IUD can cause adhesions or damage to other organs over time.

Now, let’s talk about the emotional weight of this. Because this isn’t just a medical issue; it’s a psychological one. When your body betrays your expectations of safety, it triggers a deep sense of vulnerability. You might feel angry at your doctor, angry at your body, or just exhausted by the whole process. You might worry about the cost, the time off work, the discomfort of procedures. All of these feelings are valid. Give yourself permission to feel frustrated. You didn’t ask for this drama. You chose a method of birth control that seemed convenient and effective, and now you’re dealing with the unexpected fallout. 

But here is the reframing: This is not a punishment. It is an intervention. Your body is signaling that this particular tool is no longer fitting your current anatomy. Perhaps your uterus has changed size, or your hormones have shifted in a way that makes the IUD less stable. This is your body telling you it’s time for a new strategy. Embrace that agency. You are not a passive recipient of medical events; you are the director of your health plan. Once this is resolved, you get to choose again. Maybe you try a hormonal pill. Maybe you switch to a copper IUD. Maybe you explore non-hormonal options like diaphragms or fertility awareness methods. The point is, you are back in the driver’s seat. The uncertainty ends when you take action.

Looking ahead, how do we prevent this from being a source of ongoing anxiety? Regular checks are non-negotiable. Make it a ritual. Every time you finish your period, take two minutes to check your strings. Use a mirror if you’re anxious about reaching in. Or better yet, ask your partner to help you check. It can be a moment of intimacy, of care, of mutual responsibility. It breaks the taboo around discussing bodily functions. If you can’t find the strings, don’t panic immediately. Wait a day or two. Sometimes they retract temporarily. But if they’re still missing, call your doctor. Don’t wait for your annual check-up. 

Also, pay attention to your body’s signals after insertion. If you’ve had recent childbirth, your uterus is larger and more elastic, which increases the risk of expulsion. If you’ve had multiple births, the risk is higher. Be honest with your provider about your history. If you experience severe cramping shortly after insertion, mention it. Early detection prevents late-stage panic. And remember, no method is perfect. IUDs are highly effective, but not infallible. Understanding their limitations doesn’t mean you shouldn’t use them; it means you use them with awareness. Awareness is power. It turns fear into knowledge. And knowledge is the antidote to the panic we started this episode with.

Take care of yourself, beautiful. Check in with your body, listen to its whispers before they become shouts, and remember that you are never alone in this messy, magnificent evolution. Breathe through the heat. This episode is general information, not medical advice — please talk with your own doctor about your health. Until next time, I’m Belinda Rosales, and I’ll see you in the next conversation.
