possible implantation bleeding?

Omg I'm 11dpo and think I may have experienced implantation bleeding. Never spot and af is normally regular as they come - not due till Monday!! Kind of freaking out a bit! Ha ha. Question is do I tell my hubbie or is that getting his hopes up? Also resisting testing yet as lots say you have to wait a few days to get a bfp... eeeeek!!!! 😊🤞🏻baby dust to anyone else in their tww. It's painful this isn't it! ✨
