Alamak, I totally understand your worry lah, especially being a first-timer! A few of us mums in the group were in the same boat, one girl was 40+ weeks before anything happened, and her baby came perfectly fine. The thing is, due dates aren't actually fixed dates, so don't panic yet; your doctor will monitor you and let you know if anything needs to be done. Best thing is to just ring your clinic or hospital tomorrow and let them know you haven't felt any signs yet, so they can check you properly and give you the exact next steps, they might want to do a check or induce depending on how things are going. In the meantime, try to stay calm and do the normal things (walks, rest, eat proper), stress can make it harder for your body to do its thing!
