I am getting white discharge without pain or irritation as i m 12+ week pregnant?

Probably normal: It is common to have some vaginal discharge. During pregnancy that discharge often increases. If you do not notice vaginal itching or irritation and there is no abnormal odor associated with the discharge then it is probably normal. You should expect the discharge to increase as the pregnancy progresses. If you have gushes of fluid or if your clothes become wet from the discharge - see your doctor
