Intrauterine devices (IUDs) are one of the most effective forms of birth control, lasting anywhere from 3 to 10 years depending on the type. But if you’ve never had one before, you may be wondering: what happens after an IUD insertion?
Here’s what you need to know about common side effects, recovery, and when to check in with your doctor.
How Is an IUD Inserted?
Insertion is usually quick—often less than 5 minutes:
- Your provider reviews your health history and may screen for STIs.
- The cervix is gently opened with a speculum.
- A thin applicator guides the IUD into the uterus.
- Strings are trimmed so they rest just inside the vagina.
IUDs can be placed at any time in your cycle and are often inserted right after childbirth or miscarriage.
Cramping After IUD Insertion
Mild to moderate cramping is the most common side effect.
- Hormonal IUDs (Mirena, Kyleena, etc.) → often reduce cramps and bleeding over time.
- Copper IUD (ParaGard) → more likely to cause heavier cramps, especially in the first few months.
Most cramps improve within 3–6 months. OTC pain relievers and heating pads often help.
Bleeding After IUD Insertion
Spotting or irregular bleeding is normal for the first several months.
- Hormonal IUDs may lead to lighter periods—or no period at all.
- Copper IUDs may cause heavier bleeding at first but usually improve.
Contact your doctor if bleeding is heavy, lasts longer than 6 months, or comes with dizziness/fainting.
When to Call Your Doctor
Most side effects are temporary, but you should call your provider if you experience:
- Severe or worsening cramps
- Heavy bleeding that doesn’t improve
- Fever or foul-smelling discharge (possible infection)
- Pain during sex
- Feeling like the IUD has shifted or strings are missing
Recovery Timeline: What’s Normal?
- First few days: Cramping, spotting, mild discomfort.
- First few months: Period changes (lighter/heavier depending on IUD type).
- After 6 months: Your cycle usually stabilizes.
