Girlfriend keeps smelling chlorine...

Alright, so my girlfriend is 10 weeks pregnant and for about 3 weeks now, she keeps saying, "I keep smelling chlorine." No, she's not sniffing bleach or anything. We will be in the car and she'll say it. Or be in bed and she says it. Is this normal? Is it something to be worried about?
