Had anyone experienced preterm labour. I'm 28 weeks and was admitted to hospital a couple of days ago with contraction like cramps, my cervix was closed which was good. I was allowed home but told if it got worse again or babies movements reduced to call back. This morning I've got period like cramps and lower back ache and just don't feel right. The baby isn't moving really but its still early. I dont want to waste the hospitals time if its nothing. Has anyone else had this?
