What if you can't feel the IUD strings?

The most common reason that a woman doesn't feel the strings is that they are tucked just inside the cervical opening, or are high in the vagina. However, because missing strings could mean a missing IUD, a woman who can't feel the IUD strings should consider emergency contraception if she's had intercourse in the last five days, and should use a back up method of Birth Control until she's confirmed that the IUD is still in place. Your health care provider can do an exam and, if necessary, a very brief ultrasound to confirm the location of the IUD.

It may have fallen out and you are then not protected from pregnancy. Go to the doctor and get checked, you should have an annual check anyway.

It may be that your IUD has become displaced or fallen out. I suggest you ask for a scan to see what has happened as you may not be protected at all from pregnancy.

Go and see your doctor immediately because if you are pregnant, the IUD needs removing immediately because it can harm the baby
