Sayang, rasa sakit at perut nampak lain sebelah sebelah memang boleh jadi normal sebab ligament stretching and baby position lagi, tapi since you're concerned better check dengan doctor just to be sure kan, especially kalau sakit tu persistent or parah. A few of my mum friends experienced yang sama time 16 weeks, tapi some of them ada round ligament pain yang memang one-sided je, so it can be reassuring to get the green light from your gynae yourself!
