Adui, memang ada ja mums yang macam ni! A few of my mum friends actually had faint lines or even negative UPTs at first, tapi ujian darah di clinic baru confirm they were pregnant, especially kalau test terlalu awal or urin dia encer. The hormone levels boleh ambil beberapa hari lagi to show up clearly on test strips, so don't stress, it happens la. Kalau you suspect you're pregnant, memang better to see a doctor or go to clinic for blood test (hCG quantitative), much more reliable than home UPT, and they boleh confirm exactly how far along you are. Ramai mums go through this, so you're not alone!
