Should I test (cp last month)?

I had a chemical pregnancy Sept. 25 and bleeding lasted 5 days (doctor said HCG was below 3 on Sept. 30). Should I be counting that as a period? 
I have been having light cramping, feeling extra tired (napping when I never nap), sore nipples, heightened smell. If the CP counted as a period, then it's been 31 days since the start of that period...part of me wants to know, but part of me is scared of the results (either way).
