An IUD is put in by the doctor and made to fit so it wouldn't come out of place unless it was put in wrong, but I doubt that would happen.
If you go to full term the IUD will probably come out when the baby is delivered.
I think you need to see your doctor.
An IUD does not tickle. It is not something you feel when it is in place.
The IUD does not "float," but generally remains in place at the top of the uterus.
Because it is securely attached to the IUD, an IUD string is unlikely to fall out. If you find your string is missing, contact your health care provider and use a backup method of birth control until you confirm that the IUD is still in place. A missing string can mean the IUD fell out without you knowing, but typically the string just moved up into the cervix.
Weight change will not affect the location of an IUD
go see your doctor. Pregnancy tests often give false negatives, but rarely give false positives. Or there could be a problem with the IUD which needs sorting.
An IUD removal will not cause hormonally-based hot flashes.
No, Mirena is made by Bayer and Paragard is made by Teva.
Very very very very unlikely. Purely down to the IUD. With an IUD, protection is something like 99.99999999%.
Yes and it can cause serious problems if you become pregnant while the IUD is in place.
A woman should keep an IUD in place until she wants to conceive, until the hormonal IUD reaches the end of its useful life, or indefinitely if she is not concerned about the IUD's effectiveness.
