Am 37 +3 with 2nd baby and today I had a bit of upset tummy and then felt off all day but tonight I have started to get a few twinges and pain in lower pelvis and round sides and a bit in my lower back baby is moving normally but my belly does go hard when the pain comes is this labour starting or Braxton hicks ??? I honestly dont know as last time I lost mucas plug and contractions started quite strong that I knew i think but i cant remember as this was 4yrs ago any help much appreciated x
