Maybe a little reassurance will help. Brown-Pinkish spotting at 9.2 weeks preggers.?

I discovered yesterday afternoon that I had a brownish-pink discharge and very little cramping. Here's the thing, my breast are still full and still hurt. I bought another pregnancy test today to see if my HcG levels are still present and the PG test was VERY positive. Several years ago i did have 2 miscarriages and they both started out with bright red blood. I have looked on the internet for so many answers but I just need some fresh ideas. I am hopeful that this is nothing, but preparing for the worse. I am actually pretty relaxed and know that whatever happens, happens. I have an appt with the ob on Monday. I will not go to the ER and sit around for 6 to 10 hours unless i start gushing red. ugh. Sometimes one need a little reassurance but be honest. I do have a 5 year old son and will be 38 when this one comes around. Thank you
