I have discovered a drop of sticky white liquid from both breasts while coitus. It's not spontaneous it's only occurs Post squeezing nipples, only 1 or 2 tiny drop, Post 2 days it's not going away, i have regular periods and i am not pregnant. My coming period is due in 3 days from today. Can anyone tell me what it is and do I l need to worry is it is a sign of something worse i am really worried and freaking out and checking do that checking making it worse
