thank you for asking., the symptoms you mentioned are hall marks of IUD. give it some time, she will get used to. but PIDs (pelvic inflammatory disease
) and all these mood swings are attatched to this mode of conception.
if the pain and crampings and mood swings are un affordable see the gynae obs people and ask for the shift in contraceptive
techniques. There are many to pick from.
They will select what is best for you
