We’ve seen from the previews that her character is pregnant in the movie; was she pregnant in real life at that time too?

No she wasn’t pregnant but she had just given birth to her son.
The actress landed the role of Kate Connor in the fourth movie in the Terminator franchise not long after giving birth to her son Theo and still had her post pregnancy figure. As for her losing weight on set, she said: "Naturally just after a woman has a baby she starts to lose weight. "McG was throwing cookies at me the whole time, ‘You’re still eight months pregnant in the film! Be careful! Continuity!’"
p.s.- I thought she was pregnant too.
I heard/read that she was about 4 months pregnant during the filming of "Spiderman 3"…
