Oh dear SPB.....
sorry cant really advise you to do anything - it just kind of happens all of a sudden......
bit like when you go into labour really
now did you get that homework done last night?
fwiw scrubbing the floor on your hands and knees will help to open your pelvis and get baby into a good position, so maybe T is trying to help after all bless him
take care of yourself - wishing you lots of luck for the big event xxxxx
