Slow slow early labour

I've been having tightenings since Sunday and they have got steadily worse since. Yesterday I had loose bowels and went to a routine midwife appointment. I'm 37 weeks +5. She said he head was right down now and possibly in early labour. Things cooled down yesterday evening but today have started to progress again but still not very fast. I've had loose bowels again today... I've tried gym balls, nipple stimulating, sexy time. Walking. Anything else? Also when would I ring the midwife to let them know? Sorry for tmi.
