Bacon smell?

[Tubbytiger]

Hello,

I have a female syrian hamster who is about 10 months old. Every now and then she kind of gets a bacon-ish smell. I was thinking this was related to her 3-4 day cycle and that I am just noticing the smell. My boyfriend can't smell it though when I do and I am just worried that it might be something else. But she is behaving normally and eating and drinking just fine. She did bite me today but that is only because I woke her up to check on her (I normally do not do this), so that was her only "odd" behaviour. I just want to make sure it is not wet tail or something else. Could this be possible? Should I just take her to the vet?
