I'm 39 weeks tomorrow, for 3 days now I've had constant period pain and lower back ache! Last night these pains actually woke me up more than once and I was so uncomfortable! I'm getting sharp stabbing pains also down there with the period pains, this morning I was also sick after drinking my cup of tea :( I've had lots of braxton hicks last couple weeks which have started getting more intense but not too painful. Could this all be the start of labour?
