15 weeks light bleeding

Taryn
I'm 15 weeks and 3 days pregnant.  I've been spotting with brownish blood all day.  I have a high deductible insurance plan, so I'm cautious about calling the doctor because I know she'll make me come in.  Is brownish blood concerning?  If it was red, I would definitely call, but I'm thinking brown spotting is fine and normal.  Thoughts?
