Yeah typically medical reasons or overdue. You do not want to be induced just because. I am avoiding being induced at all costs unless absolutely necessary even though i can't wait to meet my little man. From what i learned its more painful and can lead to c sections or other unnecessary things.
My Dr offers induction at 39 weeks, so it won't hurt to ask.
You could be induced to high blood pressure, baby stopped growing in your stomach, gestational diabetes, you go over due... lots of reasons.
I dont think she can induce you without medical reasons. My doctor will induce me because I have GD.
