Oh, how I feel for you! My DH lived abroad when both of ours were born. When I had DS he came back the day before my due date for his 4 week paternity leave, and day after day passed and no baby! I was SO desperate! I tried everything you have mentioned, as well as reflexology and acupuncture. I had at least 7 sweeps... Nothing worked! In the end, I gave up trying to start labour and decided to chill with a glass of wine (rare treat as it is when pg!) and some pregnancy friendly sushi. A few hours later I went into labour!
I went into labour naturally with both of mine, but both were 12 days late and I had to fight against being induced with my DS (policy was to induce at term+10). I just did not like what I had read about induced labours - read up before you accept it so you know what to expect.
Anyway, fingers crossed that won't be needed!!! Lots of labour vibes coming your way and hopefully you will go into labour tonight!
