Did they send the urine out to be checked? There have been plenty of times I didn't even know I had a UTI until the doctor called back with the lab results and put me on medication.
You need to go to a different doctor did they check you for stds. I have had the same problem and had an infection they had to treat me and my husband for. With creams and antibiotics. I also did develop a uti. And neither me or my husband have had sex with other people. We have been together for 24 years. So I would say go back to the doctor and be more persistant. Did the do a vaginal check on you? Do not let it go because if you have some form of infection it can effect you female organs and may cause you to become infertile.
That is just it. It doesn't hurt when i go to the bathroom and I went to the doctors and it shows no Urinary tract infection. and I do drip clowdy drops after I pee. and the smell when I am done is so strong. I never had this problem when I was sexually active. men suck :0)
You could have a urinary tract infection but it just hasn't gotten to the point where it is causing you pain while urinating. You should go and see your OB/GYN as soon as you can. They can do a urine test to see if there is bacteria present.
