Prenatal vitamins caused this strong odor in my urine.
sounds like a uti, but strong urine odor can also be from what you're eating. get some uti strips from the store and test for yourself if you have a uti as well as see your progress as you are doing the antibiotic treatment. sometimes our urine and fluid smell weird during pregnancy too. also, ask your doctor for a kidney panel blood test to see if your kidneys are aggitated by infection.
I am wondering if this is more of a vaginal infection? If that is the case, perhaps the medication is not the proper one. I would call your doctor and make an appt. as soon as you can get in and have it checked out. Good luck and I hope eveything goes well.
