Eh ada jugak yang experience ni! One of my mum friends had placenta previa (uri yang turun) around 20 weeks, tapi alhamdulillah normal balik after a few scans, memang stress la masa tu, tapi doctor kena monitor closely je. The important thing is keep going for all your check-ups and jangan lift heavy things or anything yang boleh trigger bleeding, sebab risiko dia tu mainly bleeding in pregnancy atau during delivery. Definitely kena discuss with your OB/GYN because depending on how low it is and how far along you are, they might recommend bed rest or even planned C-section nanti, bukan scary thing, just precaution. Have you had a scan recently? That's the clearest picture to see exactly where your placenta is positioned sekarang. Hang in there, mama!
