I’m 39 weeks today

Had a NST and pelvic exam yesterday showing that me and the baby are healthy and on track.

2cm dilated, 70% effaced and my OB gave me a membrane sweep to speed things along since I’m suffering from painful back aches.

Should I masturbate and have an orgasm to speed things along? I’m not in the mood for sex with my husband or anything involving penetration because the pressure down there is heavy.

Thoughts? Experiences?
