Risau tu normal je, especially masa week 24, perut keras tu mostly Braxton Hicks contractions, tapi mix darah dengan keputihan memang kena follow up dengan doctor lagi untuk pastikan semua okay, sebab walaupun doktor dah cakap pasal placenta position, better safe than sorry kan. A few of my mum friends went through similar and after checkup again semua smooth je, so jangan stress too much tapi do get that follow-up appointment sorted soon, doctor akan monitor placenta and cervix, and that peace of mind really helps!
