What should your cervix feel like before labour begins?

Ok - i know it's not recommended to prod around the cervix area too much but i'm interested anyway. What should the cervix feel like as labour approaches? Does it get higher or lower and does it have a distinct shape?

When in the shower this morning i had a bit of a feel and could just manage to reach what i think is my cervix. It was kind of a little pointed, like the tip of a nose or something. Was that it and what would that shape/height mean???

I'm due in just over a week so i'm praying that something's beginning to happen down there (have had the on and off period like cramping and cervix pains, extra discharge but no plug, nausea, softer no 2's but no diahhrea...). Been doing stacks of walking, sex, RLT and EPO so something's got to give soonish surely!!!

Any advice will be appreciated :)
