waiting for due date

My 1st pregnancy I delivered in 40wks + 2days and had to go through emergency csect. Now for 2nd pregnancy I'm at my 38 wks + 3days but still no signs. Been very active throughout both pregnancy and still working up till now. Pretty anxious lately as worried that I will have to go through induced labour and e sect. Any tips to induce labour naturally? Ps: my job requires me to walk alot.
