Membrane sweep

Makayla • Addison Suzanne💞🎀
Had my membranes stripped yesterday, I am 39+4 and I have read so many things online saying it's not effective and then some say it is effective. All I am is now cranky, crampy, uncomfortable and my lower back hurts. Someone tell me it might actually work. 
Also; I have lost a bit of my mucus plug, since after the sweep and I'm still losing it.
