Missed period

Eh susah betul kan bila timing jadi tak regular mcm ni, loya dan pening boleh jadi hormonal jugak, bukan semestinya sign pregnant. Since your UPT was negative on 23/2 but period baru datang 27/2, most likely yang you're experiencing adalah late period dengan flow yang agak berbeza (the dark red and clotty part bole happen when period delayed). But since symptoms like nausea dan dizziness persisted mid-Feb, better you see your GP or gynae to rule out anything else, could be hormonal imbalance, stress, atau just an off cycle, tapi they can check properly and give you peace of mind. Jangan worry sangat dulu okay, but don't wait long to check in with your doctor.
