36+2 weeks and pinkish white discharge.?

hi all! im 36+2 weeks pregnant and ive noticed for the past 2 days, ive had very very light pinkish discharge after i go to the bathroom. no blood in the toilet or anything, only on the toilet paper. (sorry if this sounds like tmi). no symptoms of labor or contractions.

is it something that i should call my doctor for? or something i should be concerned about? or would you not be concerned unless it was a lot of pink/ red discharge or blood?
