36 week checkup, 1cm dilated cervix soft

Am

Baby measured 9lbs 1-2 oz.. Head full of hair. Lol. Im 36 weeks 4 days, my next appointment is in a week and its my call on whether I want to do c-section or induction at 39 weeks, or.. go naturally. Trying to stay away from induction, also trying to keep from having a c-section, I want to go naturally but not at 40 weeks lol. Thinking of trying to get labor going at 37 weeks, that way if he is 9 pounds I can still deliver naturally without him getting any bigger. Any suggestions? And also they said my placenta looked aged?? Anyone else told this? Trying to finish last minute sterilizing and bags packed before trying.
