I would still get checked out hun even if it when your DH gets home, because IF it is the beginnings of labour they may have the ability to stop it, and you seriously don't want to go down the path of have a prem again if it can be avoided, so much better to bake them to term. Also keep in mind that your body has laboured before and things can happen a lot quicker the second time around. With DD I had no warning, waters just ruptured and by the time I got to the hospital I was 7-8cm and she was born no long afterwards. Take care and keep baking xxoo
