Eh congrats! Double line tu memang positive, even if samar-samar pun sama je, mine was super faint jugak dulu haha. Best la kalau terus jumpa doctor untuk confirm dengan blood test, sebab sometimes UPT boleh jadi faint kalau terlalu awal, tapi chances are you're pregnant! A few of us tried retesting 2-3 hari kemudian kalau masa tuh betul-betul awal, and line naik lebih jelas, tapi honestly just see your doctor to be sure, they can do a proper check and confirm everything.
