Hey there! How exciting your journey is nearly over - or rather just beginning!
I was induced for my first, and not for my second so I completely relate. But as they say to first time mums, - you'll know! It's all heading that way and it could be happening now as we speak or could be a bit of a way off! Even though you were induced your body still has been through this baby creating experience before and somehow, for me anyway, you just start know when you're on for real. I'd go roughly by your due date on the whole.

If you're not sure, I'd say you've got a bit of time to go! I felt like you described on a Wednesday at work, and had TheStar on the Friday. She was 3 weeks early by the doctor's dates, but spot on by my due dates! OOO! it's so exciting, you've nearly got your new baby!!
