Aiyoo sabar je dulu, mungkin cycle kamu memang jadi irregular sometimes, stress, diet changes, hormonal fluctuations, semua boleh affect timing! A few of my mum friends pun pernah delay sampai 10-14 hari then periode datang je, so you're not alone lah. Tapi since dah 7 hari lewat and you're having symptoms, better go see your doctor or re-test in a couple of days, they'll confirm what's happening and put your mind at ease, okay? Jangan stress sangat dulu, usually ada logical explanation je
