I'd say only do a tidy if you want to... and can be bothered!

I think each MW will approach the 40wk check differently - did she give you any indication at your last appt of what to expect?

At my 40wk appt, I know my Obs is going to do an internal and possibly a stretch and sweep, because we have discussed it. I am huge and getting very sore and not sleeping much at all, so I am keen to see if anything is happening down there.

But my sister, who went to 41+3, did not have an internal before she went into labour. She and bubs were happy so the Dr let her be.

But if you are not comfortable having an internal, or if you are happy to keep waiting and baby is all good and happy, then there's no need for an internal.

Up to you really!

ETA - good luck!!
