If i create a game using my 4 month pro trials, can i then puchase pro after it's partially developed and continue work then sell it?

I am aware I can not publish my game if i only use the trial. But can i start developing a game using my trial then continue work and publish my game by purchasing pro when my trial expires?
To my understanding I can but I want to be 100% sure.

yep I think you can start it then when ready go pro.
