Thanks for query,
1,After 1-2 years you should change iucd,
2,usually there shoud no pain while sex,there may be some infection or some problem in your genital tract,go for ultra sound
3,any lump small or big in the breast,discharge coming out from nipple,non healing ulcer in the breast,lymph
nodes enlargement in axilla
,change of breast shape all of a sudden.
Presence of these signs does not mean one is having cancer but to rule out cancer one should go for breast examination and mammography
ok and bye.
