Is it normal to spot while pregnant?

I’m pregnant with #5 (8 weeks today) and have spotted a few times over the past 2 weeks. Red blood, but then goes away on its own quickly. No pain or other symptoms. Today I’m spotting again and I’m starting to get worried that there’s something wrong with maybe me instead of the pregnancy itself? Has anyone had this? I’ve never had spotting like this with my other pregnancies. I can’t get into my OBGYN for my first appointment until August 7th.
