Chemical pregnancy? 🥺😞

Sierra

I started testing a two days before my period at 12 dpo again at 13 dpo 14dpo 15dpo and today at 16dpo. I started spotting at 14 dpo and it turned into what looked like a light period. Yesterday at 15dpo. I passed a pretty big blood clot and now my tests are negative. Could this be a chemical pregnancy?
