(TMI) Spotting during 7 weeks


So yesterday after I wiped I noticed light pink spotting and was told by my mother it's common and I shouldn't worry. But as the night went on and into this morning, the spotting is continuing but it's now brown. I have no cramping along with it and can't make an appointment with doc yet since insurance is still being processed. Is this common? I'm 7 weeks today. I don't remember this happening with my first pregnancy, so I'm a bit worried.
