worried

Brittney
Hi, sorry if this is tmi, but I have been spotting for a week now and nurse said that it is fine as long as I'm not bleeding so much where I have to change my liner every 15 minutes at first it was red blood but now it's brown has anyone ever experienced this? My first pregnancy I had NO bleeding so this freaks me out a lil I can see the dr till I'm 8 weeks I make 7 Thursday. Thanks in advance!
