Due date is a round about time for delivery. Lot of factors come to play that when your baby is ready to come out. It is not something that you should worry about. In India, generally they wait for a week more than your EDD and induce you if till 41 weeks you do not have labour starting on its own. You should go see your doctor at most by day after tomorrow. Even in lockdown, doctor appointments for pregnant women is considered essential. You can easily go without anyone stopping you. I went to 2 of my appointments during lockdown. Make sure you get your doctor's phone number to call in case of emergency and also ambulance number ready at hand.
