when a mother plans her c - section, what week do they usually plan it for? just wondering

There was a time when they did c sections at 38 weeks not to long ago I know when I was pregnant with my oldest kids that's when they did em...Man so much has changed since I had my last kid I'm beginning to think I'm gonna hate being pregnant this time

39 and up cause mine is planned for June 20 and I will be exactly 40 weeks

Usually the 39th or up or unless there's a medical reason to have it earlier than the 39th week
