Wa'alaikum assalam sis! Okay so sugar in urine boleh jadi tanda a few different things, some boleh normal, some perlu check with doctor. At 33 weeks, this is something you really should mention to your gynae at your next checkup, or even call the clinic today to be safe, okay? Don't worry yourself too much, but jangan delay jugalah. Your gynae will do a simple test to figure out what's happening and make sure everything is okay for you and baby. A couple of mum friends I know had this and turned out fine after getting checked, the doctor just needed to monitor them a bit closer, that's all. Better to confirm than guess-guess, kan? Take care, and do get it checked out ASAP!
