You can I know they did mine due to being dilated already so what's the worst they can do say no? You know what I mean? I'll be 37 weeks my next appointment as well and they are doing a growth scan my strep b and checking for dilation so maybe I will get swept as well. I am hopeful because this little girl is definitely taking her toll on my body. LOL
It depends on the situation. With my first I was 38 weeks and 2 cm, by 36 hours later I was 4 cm and induced. I have seen some get them as early as 36 weeks.
