Does the urine smell strange during early pregnancy?
"Yes some women have found that when they are pregnant their
urine becomes darker and can smell stronger than usual. There a few
potential causes of this. Pregnant women tend to have a greater
sense of smell and taste so if they may be able to better smell
their own urine, even though it actually hasn't changed. Some women
believe that they can smell the hormone that is produced and
released into urine. That hormone is called the human chorionic
gonadotropin (hCG), but it is unknown if women can actually smell
the hormone or if they are just smelling stronger urine, or as
mentioned above, smelling more of their regular urine. Another
reason your urine may smell stronger is because you need more water
than you are usually drinking. Pregnancy requires more hydration
than you may usually need, not only does the baby need water but
the embryonic fluid that surrounds the baby has to some from
somewhere.
The more water you drink the more water will be released into
urine, diluting it and thus reducing the smell. If you drink less
water, or require more water due to pregnancy, or even because you
are exercising more, then your urine will smell more like ammonia
then is may normally.
While stronger smelling urine can be a sign of pregnancy, it is
not a useful test. Visit your doctor for a blood test, or try a
home pregnancy test. Take the home pregnancy test in the morning
when the level of hCG is higher in your urine as home pregnancy
tests test for this hormone."
