Boleh je, tapi kena gentle dan follow your comfort level lah, a few of my mum friends still did, tapi they were careful dengan positioning dan tak force anything yang terasa sakit. Best la tanya your doctor or midwife directly sebab setiap pregnancy different, ada some yang risky depending on your cervix condition or if ada complications. Better safe than sorry kan, especially first time mum, doktor boleh kasih proper guidance based on your actual situation.
