35weeks +4days is this the start of labour?

For the past two days, i really feel like the baby has made his way down,(this feeling gets worse when I walk). I’m also experiencing on and off tightening and a dull achey feeling coming from my uterus area. Almost like twinges?? Increase in discharge but no sign of waters breaking etc. I’m also very restless at night. My baby is currently measuring at a week or two in front as they are saying he’s going to be big! Do you think this could be the start of early labour signs?? Thanks xx
