Hai! Yes, lah actually, a few of us dalam group chat tengah cerita pasal ni jugak. Most of the time, hCG levels rise pretty quickly after implantation, so kalau delay period dah jelas (like 1-2 weeks), UPT usually boleh detect positive already, tapi ada juga mums yang mungkin implantation lambat sikit, so they got positive results a few days atau seminggu lepas period delay jadi it varies from person to person. Best approach is kalau delay period na clear, just do the test, accuracy tinggi dah at that point lah!
