to test or not to test?

Heather

On the 19th, I woke up and took a test. I got this faint positive. As the day progressed, I started spotting. I wasn't worried til it turned bright red & had tiny clots in it. Barely, but still clots. I assumed I had a chemical pregnancy. However, this "period" came with none of the usual symptoms. Plus, it only lasted a day and a half, if that. I'm wondering if I should even bother testing again? Or if I should just wait and see? Any ideas?
