I saw my OB today and he said that the babys head is 2/5's in my pelvis and im currently 35 1/2 weeks. What does this mean? Could i go early?

i have started to feel pressure down below and it has been harder to walk over the last few days, feel like running to the loo, but there is hardly anything there 8-[

Im a first time mum, so would appreciate any feedback
