Adeh, memang pening gila dapat negative test tapi period tak datang kan! A few of my mum friends went through this, sometimes the hormone levels belum tinggi enough for upt to pick up, or badan tengah stress/hormonal imbalance je. Since dah 25 hari late, boleh try test again dalam few days or better lagi, gi check dengan doctor kat clinic, they can do blood test yang lebih accurate, so you'll get proper answers and stop the guessing game! Hang in there, sis, semua jadi clear soon enough.
