Membrane sweep?

A* • Pregnant with my first 🍼❤️💙
Hello everyone so today I'm due to see my midwife I'm 40 weeks exactly with no signs of baby boy coming soon midwife said at 38 weeks I can have the sweep done at 40 weeks just let her know when she comes but I've been thinking over past 2 weeks and still haven't made my mind up it 2am and can't sleep thinking about it! Some people say it was painful and worse thing they done and some say it was nothing I don't want to force him to come if he's not ready? What does everyone recommend do I or don't I and just wait till little mans ready?
