How do I know if labor has started? What do contractions feel like?

Nicole

I'm a FTM due September 6th and I am very curious and anxious about the labor process. How will I know it has started?

I had my appt today and my doctor asked me if I was considering getting induced and that I had to tell him soon to schedule.

I want to go into labor naturally.

Thank you if you took the time to read :).
