Bella

Im so darn confused so im 3days late i tested yesterday it was negative. I just went to use the restroom and noticed a weird sticky creamy whitish yellow egg white mixture with a few streaks of blood very tiny...never happend before around this time frame or with any of my pregnancies..usually implantation bleeding is quite obvious with all other pregnancies...im feeling weird cramping pain very mild and twitching maybe.its.gas not sure but very confusing...any ideas so i can calm down a bit or could it be my period coming?
