Strange Spotting/Discharge?

I just turned around 7 weeks and this morning when I wiped I had this brown/slightly pink spotting/discharge. 
I called my ob and the nurse was like we can't do anything for you just go to the hospital if you start bleeding heavy or cramping. And no sex. 
Just to keep my appointment next Tuesday. 
I was wondering like, you don't want to check for BV or anything else just in case? 
But anyways has anyone had this and been just fine? I'm making myself sick worrying about it because I love my baby so much already. I just want to know he or she is okay.
