advice please

I'm 36 weeks and 2 days with my 3rd baby. since 28 weeks the head has been down but not engaged. these last two weeks my bump has dropped significantly and now (sorry for tmi) my betsy(vagina) feels as though it is falling out of me it feels swollen and very fat and yeah just disgusting as if it does not want to be in my body. does this mean baby isn't far away? or have I still got to feel like this for another 3 1/2 weeks?
