I felt huge pressure around 7cm but it got ridiculously hard to ignore after awhile and while I was trying to stop it on midwife advice my body was pushing regardless which made me exhausted and sore. I kept saying I needed to push but the midwives insisted it wasnt time, turns out I was right, I ended up being 10cm and after a half hour of pushing when I felt the urge, baby was born with no tears. You def know the difference between pressure and actual needing to push feelings. I contribute my lack of tears to pushing when I had contractions NOT when they felt I should push.
