Alamak, kencing berdarah masa awal pregnancy memang scary! A few of my mum friends experienced this too, and most turned out okay, biasanya memang infection (UTI) like your doc said, bukan sebab pregnancy itself. Tapi since yours is bleeding, definitely kena follow up properly with your doctor before 8 weeks, jangan tunggu je, especially if ada symptoms lain macam pain or fever. The scan at 8 weeks memang good idea to check everything's okay, but in the meantime minum banyak air and monitor if it gets worse, if ada bleeding yang banyak sangat or cramping, go back to clinic or A&E je, better safe than sorry. Kencing berdarah banyak kali boleh jadi UTI yang kena antibiotic, and your doc can prescribe something pregnancy-safe, so don't worry lah.
