Yep usually 5/5ths means they can still feel all of the head (so it has not decended into the pelvis at all) when examining externally... then it goes all the way down to 0/5ths where the head in fully engaged into the pelvis and so can't be felt in that lower abdominal region at all. I am also 37 weeks and 3 days...two weeks ago I was 2/5ths and today I was 4/5ths as bub has changed positions so his head has popped up a bit.
