I am 36w3d. What does 'dropped' mean, can you describe it?

It means that the baby has decended further down into your pelvis, usually an indication that your labor will probably in a matter of days. The way people can tell is because during most of your pregnancy the belly is just "full" and usually centered. When you get closer to labor SOme people never drop -I never did and I was 2 weeks overdue. It really means nothing because nowdays, it just depends on the womans body.
