Sayang, reduced fetal movement memang something you shouldn't wait on, please call your doctor or go to the hospital straightaway to get checked out , okay? Better safe than sorry. At 33 weeks, any significant change in baby's movement pattern kena check with your OB immediately, even if it feels normal to you. A few of my mum friends had similar concerns and the doctors were glad they came in, some were just fine, tapi ada jugak yang needed monitoring. Don't overthink, just go get that peace of mind you deserve!
