Alamak, nadi laju time pregnant tu memang biasa, but kalau consistently atas 100 even after rest, better check with your doctor soon especially since due date dah dekat sangat, could be thyroid, anemia, atau just anxiety, semua benda ini boleh affect heart rate masa mengandung. A few of my mum friends pun pernah experience the same, and some turned out kena mild anemia lang, so don't stress too much but definitely get it checked before delivery, okay?
