Hello,
I understand your concern. There is a variety of reasons for the smell in your urine. The most common reasons are
urinary tract infections (anything involving the kidneys,
urethra, and the bladder) and vaginal infections. However, these infections present with symptoms, and you are not reporting any, so I am more inclined to think of other more simple reasons, such as: eating certain foods (like asparagus), certain beverages (excessive amounts of coffee or caffeinated drinks), certain medicines like antibiotics.
Ultimately, clam smelling urine can also be a symptom of an underlying
liver problem, or
diabetes.
Pregnancy can also be a reason. However, without more detailed information on your medical history and your lifestyle habits I am not able to give you a more accurate answer. If you cannot find the reason for the clam smelling urine in the list I gave you, I recommend you see a doctor for further investigation.
Wishing you good health and all the best.
