scary colors

Kristin
This may be tmi but I'm 6 weeks pregnant and this is my second pregnancy. I haven't been pregnant for 3 years so my memory of my first trimester symptoms aren't great. 
But being only 6 weeks and having a miscarriage 6 years ago I get nervous over certain colors with discharge. Is clear or slightly milky with a tan tint or tan blob in it normal or should I be worried?
