Don't have any sexual intercourse at all, call your doctor and schedule an appointment as soon as possible. IUD's for some reason tend to come out by themselves.
You should never remove your own IUD. You should seek a doctor immediately to test to see if you are pregnant and have your IUD or a new IUD inserted. Removal of an IUD can almost immediately leave you prone to pregnancy.
You should have your IUD removed at the end of its normal life, or when you want to get pregnant.
There are no activity restrictions when using the IUD.
Yes, the IUD can come out on its own. It's not common, but it's one of the causes of IUD failure. That's why one of the few things that the couple using an IUD has to do is check the strings at least once a month. If you can't find them, or if they seem significantly longer than they were before, you should use a back up method of birth control until you can get an exam by your health care provider.
I think IUDs are dangerous, so yes, have it removed.
If you had a hormonal IUD inserted, the lining might be thinner. With the copper IUD, the thickness of the lining would depend on where you are in the menstrual cycle. If you're reading your own ultrasound report, the final summary will give an indication if the thickness of the lining is not within normal limits.
You should remove your IUD if you want to get pregnant, if you are pregnant, or if its useful life is expired and it's time to replace it.
The IUD should remain in place and not become dislodged after sex, and there should be no pain while wearing the device.
Yes, it takes a while for your own hormones to deal with the loss of the hormones produced by the IUD.
The IUD should not make it difficult to climax. If you are worried about the safety of the IUD during sex, that could interfere with your nervous system's ability to achieve orgasm. Rest assured that sex will not make the IUD pop out, and orgasm will not cause the IUD to make problems for you.
It takes time for your body to adjust to the hormones in the IUD, the bleeding should decrease over time.
There is no medical reason to have an abortion if you get pregnant with an IUD in place. The IUD should be removed regardless of your decision. At that point, you can continue or terminate the pregnancy, but there's no need to be concerned about continuing the pregnancy if that's what you want to do.
