Sometimes Being dehydrated can cause your
urine to take on a strong
odor, even skunk like. So make sure that you are drinking enough fluids. That being said, as a nurse, I'd always recommend getting any kind of foul odor checked out. It could be an infection, and there's no way to know unless you get your urine evaluated. Sometimes you'll have other symptoms, such as frequency (hard to tell when you're preggo, lol) and or burning. Other times just odor.
