Labor shortly after stopping progesterone injections!

So I've been reading online that a lot of women who have been on progesterone injections throughout their pregnancies give birth shortly after they're last shot! Like within a week or so! I'm currently on progesterone shots (weekly) and I'm 30 weeks, my last shot will be given to me at 36 weeks! Have any of you ladies gone into labor shortly after stopping the shots?
