Sayang, dengan period delayed 4 hari, UPT yang keluar samar², and bleeding sekarang, please go see your doctor or go to clinic/A&E today je, jangan tunda. Perut dan pinggang sakit 2 hari tu perlu check proper. Better safe than sorry, especially when it comes to something like this. One of my mum friends had something similar and turned out kena early miscarriage, doktor dapat explain apa yang jadi. Masa puasa pun boleh pergi, takpe. Get it checked out, ok?
