Ahhh sabar lah, one cycle can be stressful! Negative UPT doesn't always mean you're not pregnant, sometimes it's just terlalu awal to detect. A few of us mums tried testing the next week or so and baru dapat positive line. If you're worried or period tak datang jugak, better go see your doctor to confirm, they can do a blood test which is more accurate. Jangan stress sangat dulu ya!
