Im interested to know how you knew you were in labour. Im currently 39 weeks and have been experiencing backaches and period cramps for about 22 hours now. Its more of a constant pain rather than what I would expect contractions to feel like. Ive had cramping a few times throughout my pregnancy which usually shifted when I drank lots of water but nothing is helping today. Is this normal or is it a sign things are happening? I always assumed it would be really obvious when labour started so feel a bit silly!
