Chance of being pregnant?

Look I knooow the only way to know is to test but I like hearing what other gotta say yanno. I had sex about a little over a week ago. After wards I was bleeding but then it went away and came back. It lasted a few days and was kind of a dark red/brown and wasn’t normally heavy. It lasted a few days but it was light flow idk man. Is it possible for me to be pregnant? I only ask because I just recently had a miscarriage and idk how I would cope ahaha. Plus I’ve had a horrendous cold and my food aversions and fatigue is ridiculous. I also dropped a few pounds all which happened when I was pregnant before. But then again I could just be sick. Any insight would be appreciated :)
