Sadly, nobody can tell you exactly what to expect as every labour is different. With my Eldest I started with contractions in my back, I had my show about 4hrs later, I continued with contractions but my waters had to be broken for me...49hrs start to finish. With my Youngest I had 10 days of early labour, I was in established labour before I had my show, my waters had to be broken again & she was out shortly after that.
Yes, it sounds as though baby is moving into position but when he'll decide to appear can still be anyone's guess at this stage - a couple of days to another month away...be patient & rest while you can. X
