Sayang, with spotting and lower back pain especially after your miscarriages, please see your doctor or go to the clinic today, jangan delay, okay? A positive test is usually reliable, tapi the brown spotting + pain kena check properly to make sure everything is okay. False positives are quite rare dengan Clear Blue, but what matters now is ruling out anything serious. I know you're worried after what happened before, totally understandable, but a doctor can do a scan and blood tests to confirm the pregnancy is progressing well. Please don't stress alone; go get checked out now so you can have peace of mind. Thinking of you, mama.
