Abdominal pain during pregnancy memang common, tapi since you're working as a massage therapist dan yang sakit tu spanning dari pinggng to lower abdomen, better check with your doctor to be safe lah, could be ligament pain or something else yang perlu confirm. A few of my mum friends had similar aches around that stage, tapi because you're on your feet doing massage all day, your body might be signalling overwork jugak. Don't take chances, just get it checked out so you can have peace of mind and know exactly what's happening.
