Hi mama! Okay, listen, kung may abnormal urinalysis results ka at may symptoms like back pain, better don't wait until Tuesday, go see another OB kaagad this weekend or Monday pa lang. UTI in pregnancy can get serious quickly, and Saturday waiting is risky, honestly. Pwede kang mag-walk-in sa ibang clinic or hospital if your OB isn't available, mas maayos mag-consult agad kaysa mag-worry the whole weekend, diba? You and baby deserve peace of mind, so get checked now na.
