Im 36 weeks pregnant, and for the last few days i have been getting strong period like cramping and lower back ache. i havent had a show and my waters havent broken. It isnt regular enough to be able to take timings they come and go as they please. I also get them when ive been walking any distance for example first one came when i was walking round asda, crippled me to the point of having to crouch down in the isle :'( it went away soon after i sat down though and didnt have one again until the next morning early hours in bed. This is my first and im not sure what to expect i have a midwife appointment tomorrow. but am worried that it could be early labour any help? xx
