Ay, taklah dapat judge je based on UPT yang samar² and spotting ni, banyak possibility, bisa implantation bleeding kalau pregnant, or bisa juga hormonal bleeding or cycle yang agak irregular. Since calendar mu varied (1 delay vs esok), best move is repeat UPT dalam 2-3 hari when hCG levels clearer, or just go see your doctor straightaway, they boleh confirm properly with blood test if you're anxious now je. Kalau terus ada bleeding or cramping, don't wait lah.
