Spotting?

I am 7 weeks. I have been having on and off spotting since 5 weeks and 5 days. Its light and creamy and a orangish red color. Not fresh blood or bright red. It is so weird I have never experienced this with my last two. Could it possibly be a miss carriage? If so how long until it will get heavy? I have no cramping either. I am in the process of moving so we are on the road at the moment and will not be at our location until tomorrow sometimes, so cannot see a doctor until then... idk just kinda worried, its on and off sometimes I will go a few days with no spotting and then their it is and its only when I wipe, then it will disappear. Idk just weird.
