Ooh honestly samar-samar lines can be so stressful lah! Since the Clearblue one came out clear and the other one is faint, there's definitely something there, even faint lines mean positive, but different brands have different sensitivity so yang samar tu normal. Since you're already 3 days late, best to go see your doctor or do a blood test to confirm for sure, because they can give you the definite answer rather than staring at these sticks lol, a few of us tried multiple tests and ended up just going to the clinic to confirm properly.
