After Paragard insertion, most people experience cramping and some spotting that starts immediately and can persist for days to weeks. The first few months bring heavier, longer periods as your body adjusts to the copper IUD, and this adjustment period is a normal part of the process. Here’s what the timeline actually looks like.
The First 24 Hours
Cramping after insertion ranges from mild to intense and feels similar to strong period cramps. For some people it peaks within the first hour and fades; for others it lingers through the day. Light spotting or bleeding is also normal right away. Over-the-counter pain relievers and a heating pad are your best tools during this window.
During the first 24 hours, avoid tampons, baths, and vaginal sex. Showers are fine. Exercise isn’t strictly off-limits, but most people prefer to take it easy while the cramping is at its worst. After that initial day, you can resume all of these activities.
Cramping Over the First Few Months
Cramping doesn’t disappear after day one. In a prospective study tracking new copper IUD users, cramping frequency started out between bimonthly and weekly, then steadily decreased over six months to about once or twice a month. So the trend is clearly downward, but it takes time. Those first couple of cycles often come with noticeably stronger cramps than you’re used to, especially around your period.
If cramping is sharp, one-sided, or accompanied by fever, that’s different from the dull, central ache of normal adjustment. But garden-variety cramping that comes and goes, even if it’s more intense than your pre-IUD baseline, is expected.
How Your Period Will Change
Heavier and longer periods are the most commonly reported side effect of Paragard. The copper triggers a localized inflammatory response in the uterine lining, which is actually how it prevents pregnancy: copper ions create an environment that’s toxic to sperm. But that same inflammatory process also tends to increase menstrual bleeding.
Most people notice their periods are heavier and last a day or two longer than before, particularly in the first three to six months. Over that timeframe, bleeding and cramping during periods generally improve, and satisfaction with the IUD tends to rise as the body settles in.
Spotting Between Periods
Irregular spotting between periods is common after insertion. This is one area where the news is less reassuring: research from a large follow-up study found that intermenstrual spotting didn’t clearly improve over time, and in some analyses it actually increased slightly. The number of days with spotting between periods tended to rise rather than fall.
This doesn’t mean every Paragard user deals with persistent spotting. Many people find it resolves after the first few cycles. But if you’re someone who continues to spot between periods months later, that’s within the range of normal for this device. It’s worth weighing against the benefits of hormone-free, long-acting contraception.
Checking Your IUD Strings
Paragard has two thin strings that hang through your cervix into the upper vagina. The standard recommendation from the manufacturer is to check these strings regularly, typically once a month after your period, by reaching in with clean fingers and feeling for the strings at your cervix. You should feel the strings but not the hard plastic of the device itself.
That said, not being able to feel the strings is surprisingly common and doesn’t necessarily mean something is wrong. A study on string checks found that many people simply can’t locate them, even when the IUD is perfectly in place. The strings can curl up around the cervix or soften over time. If you’ve been checking regularly and suddenly can’t feel them, or if you feel something hard and plastic, it’s worth getting checked. Otherwise, the inability to find them on any given attempt isn’t cause for alarm on its own.
Expulsion Risk in the First Year
Expulsion, where the IUD partially or fully slips out of position, happens to about 2.3% of copper IUD users within the first year. The risk is highest in the first few months after insertion. Over five years, the cumulative rate rises to roughly 4.8%.
Signs of expulsion include feeling the hard body of the IUD at your cervix or in your vagina, a sudden increase in cramping, unusual bleeding, or pain during sex. If the IUD shifts out of place, it won’t protect against pregnancy. Use backup contraception and schedule an appointment if you suspect it’s moved.
Infection Risk After Insertion
The highest risk window for pelvic infection after any IUD insertion is the first 20 days. This is related to the insertion procedure itself, not the copper. After that window closes, the IUD doesn’t increase your baseline risk of pelvic inflammatory disease.
Warning signs of infection include fever, worsening pelvic pain (not just the normal cramping pattern), foul-smelling discharge, or pain during sex that’s new and different from mild post-insertion tenderness. These symptoms in the first few weeks after insertion should be evaluated promptly.
Your Follow-Up Appointment
Most providers schedule a follow-up visit four to six weeks after insertion. This appointment is mainly to confirm the IUD is still properly positioned and to check that the strings are visible. It’s also a good time to discuss how you’re tolerating the side effects and whether the bleeding pattern is what you expected.
After that initial visit, routine follow-ups specifically for the IUD aren’t strictly required. Paragard is FDA-approved for up to 10 years of continuous use, so once it’s confirmed in place, it works quietly in the background. You’ll need to have it removed on or before the 10-year mark. If you want it out sooner, removal is a quick office procedure at any time.
What the Adjustment Timeline Looks Like
The first one to three months are the roughest. Cramping is most frequent, periods are heaviest, and spotting is most unpredictable. By three to six months, most people see a real improvement in cramping and period heaviness, even if things haven’t fully returned to their pre-IUD baseline. Satisfaction with the copper IUD consistently rises over this period as the worst of the adjustment fades.
Paragard periods will likely always be somewhat heavier than what you had before. That’s the trade-off for hormone-free contraception that lasts a decade. For most people, the side effects become manageable enough that they’re worth it. For some, especially those who already had heavy or painful periods, the extra bleeding tips the balance the other way. Giving it at least three to six months before making that call gives the most accurate picture of what your long-term experience will be.
