Hi ladies, i am due today with my second baby, (ds was born on due date). Wasn't expecting anything to happen today, so went for a walk. Whilst walking i got lots of pressure down below and felt like i needed to wee, came home, sat down for lunch and started having contractions. Have now had them roughly every 12mins for the past 2hrs. In between them i have mild period type pain. Is it more likely that walking has set off a string of strong BH or is the begining of labour? Thanks for any input x
