Bogies? Down there?! Advice please?

Jessica

So im 12dpo today and got my bfp on 9dpo (digital clear blue and first response early). Last night I got what looks like bogies....greeny/Brown cervical...Mucus when I wiped. I'm worried this pregnancy will result in a chemical as my period isnt due til tomorrow/7th. Is this a good sign or normal thing? Is it after implantation? Is it a part of the mucus plug? Please reassure me or let me know I should stop getting my hopes up that this bean will be sticky! Thank you in advance 😁
