Hai! Boleh je UPT negative pada 4 minggu even though you're actually pregnant, hCG levels mungkin still very low at that stage, especially if timing ovulation was uncertain. A few of my mum friends pun experienced this, then dapat positive result a week or two later when they retested. Best thing is get a blood test from your doctor lah, that's more sensitive than UPT, especially this early on. Jangan stress, timing lang yang tricky at 4 weeks, give it a few more days or go straight to clinic and ask for a quantitative hCG test, dey can confirm things properly.
