Been spotting on and off since 5 AM. Light pink once, brown ever since. I'm calling my doc @ 9 am because she said she wanted to hear from me if I had any bleeding whatsoever.
It really is so much easier to say "spotting is normal" when it isn't happening to you......I'm a nervous wreck.

Re: ugh......joining the spotting club.
I had spotting with both this pregnancy at 4 weeks, and last pregnancy from 5-7 weeks. My doctor said as long as it is brown, it is ok. He said it is your body cleaning out all the "old blood" to make room to house the baby for 9 months.
Easier said than done, but try to relax. Keep us updated!
