Wa'alaikumassalam sis! Jangan tunda lagi, please go to hospital or see your doctor today , okay? Keputihan dengan darah, especially at 30 weeks, plus sakit rusuk kanan kena check properly. Boleh jadi benda normal, tapi boleh jugak ada yang perlu perhatian, so jangan ambil risiko. One of my mum friends ignored spotting and turned out kena infection, she wishes dia pergi awal. Sibuk ke tidak, baby safety comes first! Teruslah ke hospital, ya.
