Just because nothing has happened yet... Doesn't mean it isn't around the corner.
Your body is giving loads of signs of getting ready for labour, it's setting it self up.
Some women progress slowly over several weeks from like 1cm then a couple weeks later to 2cm.
Some women start labour at 0cm and go from 0-10 in a few hours.
Just spend this time making sure you haven't missed something from your hospital bag, setting things ready for baby.
Make a list of people to send birth notices to. Prepare the notices so you only have to fill in the time/date/weight/length and name. Address the envelopes, etc.
Have a run through of your "nursery" and see if there is that "essential can't live without" item that you always meant to get but never got around too.
