Why is my female rat attacking the male? Could she be pregnant?

I'm unsure if my female rat is pregnant.. I don't know her age as I wasn't told when I brought her.. but she seems to be attacking my male.. what does this mean?

it does not mean she is pregnant, rats can sometimes be aggressive to each other without any good reason. pregnancy in rats lasts up to 24 days, you will have to wait until then to find out if she was pregnant (if she lives with a male, she probably is).
