Early Pregnancy Bleeding

So I have been having spotting/light bleeding since Sept. 13. I initially thought it was my period starting, but it was mostly spotting and didn’t pick up, so that Saturday I took two pregnancy tests (one digital) and got clear positives. I continued to have bleeding, so on Tuesday I was able to be seen by my OB. I had my first bhcg test that day of 182, and the second 48hr later, was 348. They said my levels increased appropriately and I’m scheduled for my ultrasound Oct. 18th, but I’m still having bleeding. It ranges from light brown spotting, to a light red flow. My periods are much heavier, with clots, so it’s not really comparable to that, but this has been going on for almost two weeks.

I’m not sure what to think and the emotional whiplash is starting to take a toll. Has anyone else experienced anything like this?
