Alamak, pulse rate machines memang boleh baca tinggi sometimes, a few of my mum friends during pregnancy jugak kena gaini, especially kalau nervous or anxiety sikit before clinic visits (you know lah, white coat syndrome!). Since your nurse's manual reading is normal dan blood pressure pun okay, it's likely the machine yang being finicky, but definitely mention this pattern to your doctor next visit so they can reassure you properly and rule out anything else, okay? Trimester 3 memang sometimes kita rasa palpitations sebab heart is working harder carrying baby, tapi good thing vitals mu check out, alhamdulillah indeed!
