Spotting at 6 weeks. Should I be worried?

I had some spotting today. It started out as a drop of red in my underwear and red blood when I wiped. But within twenty minutes it turned into rusty colored spotting that only appears when I wipe, hasn’t really left anything in a pad. Not experiencing cramps, but I do feel super bloated. I will be calling my OB in the morning, but just would really appreciate hearing that this is normal. I’m going to be anxious all night :(
