I don't believe she would be pregnant; I suppose it's possible, but she was young when I got her; only 4 - 4 1/2 weeks. It does happen though...
It was YOUR responsibility to know how to sex the rats before you bring them home. You know not to rely on petshops, they don't know anything. It's not their responsibility to pay for a spay or neuter either, it's the owners.

How long have you had her? She looks around 2 months old, therefor is very much old enough to be pregnant.
