what do you consider smelly cm?

I am 5 weeks preg having cm that is slightly yellow and I know is normal unless I'm itching which I'm not or it smells which is what I'm confused about.. It doesn't smell strong enough that I can smell it without actually putting my nose near it but when I put my nose near it, it doesn't exactly smell nice? but doesn't smell like absolutely disgusting or fishy? am I ok??
