Wanting to Deliver at 37weeks.

So, I will be 35 weeks tomorrow and I'm in non-stop pain due to having a bad back which is worsened by my giant knockers and now even bigger knockers and huge rainbow baby boy. I've read online some women have "self induced". I was wondering if any women have done this or if it's smart and safe to do... I'm not looking for any hate please I'm in horrible pain and can't walk for more then 20 minutes at a time before the pain just makes me cry. My swelling in my feet is so bad that it doesn't go down much. My big boy is measuring 4 weeks ahead as well as he's healthy and they told me everything looked great and is going perfect. I know 37 weeks is considered full term, I'm miserable and it's taking a serious toll on my body. Nothing has helped. Is it safe to try and self induce? I've read women who walked up stairs and their water broke, sex, long walks. Again please no hate I'm asking to see if it's safe to do and if not of course I will stick it out until he decides to come out on his own I'm just physically hurting to the point I can't do much at all. Thanks for the advice in advance 😊
