Implantation bleeding

Genevieve • artist/esthetician. trying for my first little baby
I had some spotting today, I'm not due to start till next Thursday my husband and I are ttc I took a test yesterday and it was negative, and now spotting today. Is this possible? Could I still get a bfp if I test again in a couple of days? Im very regular and have never spotted before. Could it be implantation bleeding?
