Adeh, 2 bulan delay dengan UPT negatif memang bikin cemas, I understand! Tapi since your doctor dah scan dan cakap rahim tebal (yang bole jadi tanda pre-period atau hormonal changes), I'd suggest book balik dengan doctor sebab sakit tulang punggung + body lethargy tu boleh jadi banyak benda, stress, hormonal imbalance, or something else yang perlu proper check, bukan just rely on one scan. Jangan self-diagnose online, get a proper blood test or second opinion from your gyno, ok? Sending you patience, these delays are stressful tapi mostly sort themselves out with proper guidance from your doctor.
