Ladybird - I'm in the same position as you, baby sometimes drops into the pelvis, but he's not engaged yet. Doc said that engagement should happen any time soon. Baby is now 6.6 pounds! he's around the 67th percentile, so bigger than a normal baby, but not huge.
Unfortunately no 3D pics cause baby was facing my spine, so all we could see was the back of his head! oh well - guess it will make it even more of a surprise to see him on D-day! I did a urine test and twice I tested positive for some protiens, so they're testing to see if I have pre-eclampsia (eek!). My blood pressure was normal though, so hopefully they're just eer-ing on the side of caution.
