Just wondering....

Why are so many people on here being induced before 40 weeks? I’m a FTM and just curious! I’m due December 31st. Would the dr. make me get induced if I don’t go into labor before then? Or is this a choice you guys make? Also, so many people talk about ways to “force” your body into labor. Wouldn’t it be better to just let your body and baby decide that on their own? Thank you for helping me understand! 🤷🏼‍♀️🙈 clueless over here 🙇🏼‍♀️
