Very light flow?

Lindsey
Hi ladies! I was wondering if anyone has experienced a very light flow in the morning and then it becomes pretty much non existent in the afternoon and evening? I was hoping for a pregnancy this month but took a test Sunday(supposed to start cycle) and it was Negative. I had a MC in October and my cycle has been heavier and not as consistent as prior to the MC. Could this be implantation bleeding or just a plain old light flow period?
