Positive na kaya?

Good day mommies. Help! Sino po naka experience nito. 4days pa lang delayed. 1st pic Oct 18 , akala ko evap line lang. 2nd pic today 6:30am then sa last pic today din 9am. Pwede na ba magpa blood pregnancy test as early as 4days palang delayed? Trying to have a baby for 10months already. 🥺 Thank you sa sasagot. #pleasehelp #advicepls #pregnancy
