Membrane sweep/ loss mucus plug

Today’s Sunday and I had gone in Thursday for induction, induction failed , I was contracting 2-3 minutes apart and on pitocin for 14 hours but my cervix wouldn’t open more than when I came in. Soo then on Friday we decided to go home and wait things out but before we were discharged I asked for a membrane sweep. Saturday I started loosing parts of mucus plug 2 good sized globs and then sunday (today) woke up and lost a giant glob (will insert pic ) . What do y’all think ? I’m also 39 weeks 4 days . Tell me your stories on getting a sweep done and loosing plug and then when did you go into labor ? How long after ?
