I'm no rat reproduction expert here but just from my experience with my own small group of females I'd say she looks preggie to me too. I usually pull mine about that stage and give them the rest of the time alone so they don't have to compete for food or water and can get lots of rest before the litter arrives.

If she suddenly delivers with the male present it'll likely be fine. I don't know if male rats know if it's their offspring or not? Lots of people leave the male rat in with the female but just be aware he may try to impregnate her again very soon after she delivers the litter. She doesn't look ready to pop quite yet though lol but you never know with rats some of them hide their pregnancies more than others.
