I'm 34 weeks with twins so at risk of preterm labour. I'm having a lot of braxton hicks which I didn't have first time round but I'm wondering how I will recognise proper labour. Last time it started with terrible diarrhoea, back ache and a show and then very slow progression. I also had a mc at 11 weeks which also began with diarrhoea and backache and progressed into contractions. I'm wondering if that's what I'm looking for this time or if it could be totally different! Any experiences?
