40weeks & no signs!

Hi mummies! going 40weeks pregnant tomorrow, but still no signs of labour😭 these 2 days i have been experiencing sudden weakness, like i dont have the energy to stand or even raise my hand & shivers (felt nauseous & had mild cramps that goes off yesterday). called KKH Delivery suite last night, but the nurse didnt know why & advised me to come down however i dont really want to stay for long in the observation ward. i missed my appointment last 2 weeks & made a new one for coming Thurs. any advise? should i just walk in to Delivery suite or wait till my appointment? really worried now. 🥺 PS: i walked alot these days, i ate everything that i want to eat hahaha! howww
