Chemical...HELP! Tmi

Nikki • Baby Boy born June 2017 💙
This past cycle I had a chemical pregnancy.... I got a positive test last Saturday @10 dpo (twice with two different tests) and by Sunday they were negative. Last test was still negative at 14 dpo. At 16 dpo I started really light spotting (mostly brown). 3 days later, I'm still what I would consider spotting. I have had a few instances of red bleeding-- once there was some clotting, although it was still very light. None of the "red" light bleeding has lasted for more than 10-15 mins tops. Is this just spotting, or is it normal for my period to be so light? Any information would be helpful. Thanks!
