So I go in today for my weekly appointment with my ob. And they tell me to get undress from the waist down. I'm wondering why am I being checked again this week, he checked me last week and the week prior to that. I thought when your scheduled for a cesearen they don't check you because they don't want you to go into labor. Anyone knows if it's true or not? Was I supposed to be checked?
