welcome to HealthcareMagic
Multiload is a IUD(intra uterine device) used for contraception
and is aavailable as Mutiload 250(for 3 yrs of contraception) and Mutiload 375(for 5 yrs).Normally it is one of the most preferred modes of contraception and is well tolerated but in few cases it may give rise to problems like
where there is more bleeding than normal but they may settle down and become normal in a couple of months.
-there can be cramps like pain in uterus
after insertion of multiload which may subside in a week and can be relieved by painkiller and if the pain persists you will have to consult your Gynaecologist.
Since you have been using the IUD for 3-4 months if the pain is daily and is bothering you please consult your doctor.
