Why do I get a dot each time I press the space bar?

[Dee]

Whilst typing in Word, each time I press the space bar, I get a full stop but
at hyphen level. Why is this? I've looked through different settings such as
"track changes" to see if I've switched something on that I don't need, but
can't find anything. It's really frustrating.

Tools > Options : Formatting marks; or just click the pilcrow button.

explanation of why you might sometimes want to be able to see these
nonprinting characters or formatting marks.
