Strange smelling urine

I think lately my pee has started to smell weird. Just in the last week or so.:redface:

I don't think the colour is any different from usual (I always dehydrate overnight and then rehydrate during the day), but this smell is weird.

I can't really describe it ... it smells strong and maybe acidic, ummmm sort of in the same way that vomit smells acidic. Bad description but I can't liken it to anything.

I think usually my pee smells sort of mildly "sweet" (not like cherries and ice cream, but sweet).

By the way, I'm not sniffing my wee, there is an odour in the air after I go to the toilet.

Any ideas? I will talk to my Ob when I see him on Tuesday, but that's a few days away.
