Start Of Labor?

So, earlier today , I was trying some different things to kickstart my labor only out of boredom & im due in 1 week🙃 The last time i went to the doctor I was 1cm dialated but my cervix has softened! What i did today was, nipple stimulation, walked 1 mile, & did some exercises! Since then i have been having Braxton Hicks which is normal for ke but ive had them pretty often today after my "labor inducing experiment" & also my vaginal area has been getting some sharp pains as if its stretching? Could i have done something? 😩 Is this the start of labor?
