Hey mama, please consider all the pros and cons of a membrane sweep before agreeing to one. Natural labour is exactly what it is - going into labour naturally and allowing the body to do what it is built to do.
I’d like to encourage you to read some articles that are out there regarding membrane sweep:

In the coming weeks, you may even start now, go on slow walks in the evening. Creating movement helps give baby room for movement - when you move, baby moves too even tho it’s a tight squeeze. Pelvic tilts and moving your hips in circles while standing or while on a birth ball help widen and prepare the pelvis to make room for baby. Give your body time and distract yourself when you get anxious or excited. Your body has a lot of work to do - from getting the hormones going, to the loosening of ligaments, to practice contractions (since your body hasn’t laboured before) and later to have your cervix efface and dilate (there’s so much more that I haven’t written here). Stay strong mama! You’ve done so well this far!
