Hello and thank you for contacting us.
If you have had Mirena
for 2 years it is quite unlikely that it has moved now. If it had though you would rather expect some blood loss and low abdominal pain
. In the case you lost it then you should be aware that you are at risk for an undesired pregnancy
since Primolut is not a birth control substance.
As for the buttocks and legs pain this could be caused by a nodule of endometriosis
or it could be a neurologic or orthopaedic problem.
Anyway the ultrasound
scan will answer your questions. In the meantime have protected sex and be careful for any blood loss.
