The device was removed and has not been placed back in for over 3 hours (it has been in place for more than 2 weeks)?

Hello, doctor.
I have been continuously using the Mirena IUD (inserted for three weeks and removed for one week) for about a year.
This cycle has been in place for 15 days (over two weeks).
After removing it yesterday, I forgot to insert it again (I had unprotected intercourse yesterday).
I realized this about 10 hours later.
Should I reinsert the old IUD, or do I need to purchase a new one? Will this affect the previous contraceptive effectiveness? What measures should I take next? Thank you.

Hello Miss 12345yi: I have limited knowledge regarding the use of intrauterine devices (IUDs), so I recommend that you refer to the user manual.
However, based on my medical knowledge, if the device has been removed for a short period, such as one or two days, the risk of infection is theoretically low, and it should be possible to reinsert it.
The previous contraceptive effectiveness should not be affected by the removal this time.
You still have a chance of becoming pregnant.
In the future, I suggest that if the device is removed for no more than 48 hours, you can use emergency contraception for prevention.

More Info

For individuals using a hormonal intrauterine device (IUD) like Mirena or any similar device that follows a specific cycle of insertion and removal, forgetting to reinsert the device can lead to concerns about contraceptive effectiveness and the risk of unintended pregnancy. In your case, since you have been using the device consistently for about a year and have missed the reinsertion after the removal period, here’s what you should consider:
1. Immediate Action: Since you have missed the reinsertion for about 10 hours after the scheduled time, it is advisable to reinsert the device as soon as possible. If you still have the old device and it is not damaged, you can reinsert it. However, if you are unsure about its integrity or if it has been out for too long, it may be safer to obtain a new device.

2. Contraceptive Effectiveness: The effectiveness of the hormonal IUD is contingent upon it being in place. When the device is removed, its contraceptive effects cease almost immediately. Since you had unprotected intercourse shortly before realizing the device was not reinserted, there is a potential risk of pregnancy. If you are concerned about this, consider taking a pregnancy test if your next menstrual period is delayed.

3. Backup Contraception: Until you have successfully reinserted the device, it is recommended to use backup contraception methods, such as condoms, to prevent unintended pregnancy. This is especially important if you have had unprotected intercourse after the removal of the device.

4. Consult Your Healthcare Provider: It is crucial to consult with your healthcare provider as soon as possible. They can provide personalized advice based on your specific situation, including whether to reinsert the old device or obtain a new one. They can also discuss alternative contraceptive methods if you decide to switch.

5. Future Considerations: To avoid similar situations in the future, consider setting reminders for the reinsertion dates or discussing with your healthcare provider about other long-term contraceptive options that may fit your lifestyle better.
6. Understanding the Risks: It’s important to understand that missing the reinsertion of your IUD can lead to a higher risk of pregnancy. If you are concerned about this risk, your healthcare provider may discuss emergency contraception options with you, depending on how long it has been since the unprotected intercourse.

In summary, reinsert the device as soon as possible, consider using backup contraception, and consult your healthcare provider for further guidance. It’s essential to stay informed about your contraceptive options and to maintain open communication with your healthcare provider to ensure effective family planning.
