When this happen, There is no relief from a ball embedded in a bunker.
If you'll forgive the "anything can happen" malarkey, not likely at all. Once the uterine cycle ends, there's no place for a fertilized egg to implant. Without implantation there can be no pregnancy.
Most likely she is not pregnant, since a menstrual cycle comes when an ovum(fertilized egg) reaches the uterus. The body recognizes the unfertilized egg and expells the uterine lining, called a 'period', and takes the egg with it. However, if a fertilized egg reaches the uterus it implants into the wall, and the menstrual cycle does not happen, due to the fact that the uterine lining is needed to accomodate the embryo. so, no, it is unlikely she is pregnant.
Broken Helix happened in 1997.
you get a detention
The zygote will not implant on the uterine wall.
Not sure about the first part of the question, but embedded IUDs can be a dangerous problem. It can put you at higher risk for uterine perforation and secondary infection such as pelvic inflammatory disease (PID). Embedding occurs when the uterine tissue starts to grow around the IUD; they should only be removed by a medical professional. I would find it strange that an insurance company would refuse to cover something that could lead to a serious medical complication down the line (maybe because it is associated with an elective procedure, i.e. contraception?), but I would consult the call line of your local OB/GYN clinic to be sure.

Nope. You can still get pregnant. It is less likely, but can happen.

Sadly, yes, it can happen.
