Tinted discharge -spotting??

Miranda
I am currently 7wks5days with my first. For the past few days, I have had what I will call "tinted discharge". TMI WARNING- it is like normal "slippery" discharge when I wipe, except it is tinted a brownish- pink color. Just enough that you would notice it on the toilet paper. I wouldn't go so far as to call it spotting as I need no protection for my clothing. I have had cramps my entire pregnancy: my Doctor said they were growing pains. Is this "tinting" normal? My next US isn't until September.
