Sayang, this really needs a doctor's check, jangan delay lagi okay, especially if it's getting worse. Left side abdominal pain boleh jadi banyak things, and since you're pregnant, kena kena confirm with your gynae or go to A&E if sakit tu teruk or ada spotting. A few of my mum friends had similar scares, and doctor kata better safe than sorry masa pregnant. Please go check today ja, your peace of mind is worth it!
