How will you feel when he says your cervix is long and closed up tight?
most people get upset they are going through pre labour pains and there is no change in their cervix.
I had weeks of prelabour pains. The day I moved house (36 weeks), which was the worst, I thought I was in labour. As it turns out I was less than 1cm dilated and not even fully effaced 9hrs after being in early labour at 39.4. Turns out my body did all the work on that day as my son was born another 9 hrs later.

It IS your body and your choice, but people do warn you for a reason. You don't have to agree with that but it isn't unhealthy to hear. The better way would be to focus on the fact that regardless of whether you are dilated or not - these pre-labour pains are there for a reason. That reason might not be evident yet and that is why the internal could be disappointing.
