IV been having irregular really painful cramps (like when your 6/7cm contraction Pains), since Thursday night, at one point they where every 3minutes for 3 hours. Now theyre every 15/20mins , sometimes stop for an hour or two but start again eventually. I'm 38+3 with my second. Did anyone else go through this? Does it mean labours coming soon? How long did it take for you to go into labour if you went through this
