Vagina Smells Like Cleaning Products

My vagina has smells like ammonia/bleach for the last few days, and I'm not sure why.

Some information that may help:

- no pain, itching, discharge or anything out of the ordinary other than the smell

- I have had a cold over the last week

- I read this could relate to dehydration so I've been drinking more water, but there's no change.

- I only have one sexual partner and we currently do not have vaginal sex, so I am pretty positive I do not have an STD nor am I pregnant.

Help?
