How do you know if bubs will come early?

I had a bit of a scare yesterday I was very over heated! Bubs was pushing down and causing quite a bit of pelvic pressure and hip pain, I called my midwife who told me to go home and cool down try reposition him but since then he has been moving a crazy amount every now and then head butting me in the cervix and kicks to the ribs. He almost feels like he wants out now!
