unable to reach cervix for a sweep at 38 weeks?

demi • Expecting our first precious miracle baby after the Mr. beat testicular cancer, an orchiectomy & chemotherapy 😍👶🏼
Second attempt at a sweep today at 39+3. Praying my OB can reach. Last week my cervix was still posterior and only 1cm, but at least soft and 70%. I just want anything to jumpstart. I have family coming into town on the 20th and I do NOT want them at the hospital. Hell, I don't even want anybody at my house for the first week after we get discharged. Anybody have luck with their sweeps?
