Hiya,

My suggestion is possibly the LAST thing on earth you feel like doing but when I was overdue and nothing was happening but feeling absolutely dreadful DH and I DTD and within 45 min I was contracting and was 8cm dilated, raced to the hospital DD was born 3 hrs and 45 min after DTD.
Admittedly it wasn't done to rock our worlds but very gently to bring on labour, desperation calls for desperate measures.
Just a suggestion, I wish you all the best, Missy
