It is much too early to make any sort of considered response.
You need to wait until your next cycle is due.

But is it possible that I am pregnant in any way by what I said happened?

I am asking should I be expecting a child?

Yes, No, Maybe

You should be expecting if you continue,

Are you pregnant this time, no one knows you are using the wrong terms, so I will assume English perhaps is not your first language and/or you are very young.

This is how you get pregnant but it does not happen every time, So you now wait most likely to next month and see if you get the period then, if you don't, try a pregnancy test then
