Aww I understand how anxious you must be, especially dengan berharap but tak dapat kepastian lagi! A few of us went through delayed periods too, ada yang eventually dapat positive test on day 12-14 of the delay, tapi ada juga yang hormones just jadi moody je then period datang. Since you've already tested on day 1, 6, and 10 with negatives, I think the best move sekarang is check with your doctor to rule out hormone changes or other causes, sebab 10 days is worth getting checked properly. The waiting game is the hardest part, but try not to stress yourself too much because stress itself boleh delay period lagi, easier said than done, I know! In sha Allah whatever happens, semoga Allah beri yang terbaik untuk you.
