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.
