The risk of puncture (perforation) is very small but does happen occasionally. Having the IUD inserted and removed by a skilled practitioner reduces the risk. You should never attempt to remove an IUD by yourself.
A Multiload IUD is a copper IUD.
The ParaGard IUD is T shaped and it contains copper.
You can get trichomoniasis regardless of whether you have an IUD. The IUD does not cause or prevent trich.
There are many ways a pregnancy with an IUD can progress, and each way increases risk to you and the foetus. If you want to continue your pregnancy, seek a second (and maybe third) opinion on whether and how the IUD can be removed. If you don't get the IUD removed, it'll most likely cause you to miscarry, which can cause bleeding--although the emotional trauma will probably be greater than the physical trauma. If you don't get the IUD removed and don't miscarry, the pregnancy could push the IUD into your uterine wall. A uterine puncture would put you at risk for pelvic infection and other very dangerous complications. There's also a chance the foetus could develop around the IUD, leading to any number of very unpleasant consequences, including late-term miscarriage and foetal deformation or death.
You can get an infection with or without the IUD. Expulsion of an IUD doesn't increase the risk of infection.
Yes, you can certainly get an IUD if you have HPV.
How do you get your IUD removed
If the IUD is not in the uterus, it has likely fallen out.
Allergy to copper or Wilson's disease are contraindications to the copper IUD that don't apply to the levonorgestrel IUD. In addition, severe anemia is a contraindication for the copper IUD, but may be an indication for the levonorgestrel IUD, particularly if the anemia is exacerbated by heavy periods.
Fertility returns to your baseline after removal of the IUD. Whether it's easy to get pregnant after removal depends on your fertility, not the IUD.
There are no activity restrictions when using the IUD.
An IUD does not tickle. It is not something you feel when it is in place.
