Urinary track infection?

Okay, I’m a sixteen year old girl. And I recently lost my virginity to my boyfriend. (Some might say I’m too young to be having sex but please do not post to tell me that) .. after a day or two of losing my virginity it always feels like I have to pee and when I do, it’s almost like cloudy and it has a slight smell to it. I told my mom, although I didnt tell her about losing my virginity because she’s strict. And I’m not on birth control. Now I overthink about going to the doctors and having to pee in a cup. It’s only been a week after having sex and I’m scared that there’s a chance I could be pregnant.. of course it’s a slight chance because we used a condom but it can still happen. If i was pregnant will it already show in the test if it’s only been 8-9 days by then? Please refrain from all the comments about me being stupid or too young. Please help!

Update ::

Yesterday I went in to the doctors and after peeing in a cup they said that they saw white blood cells in my urine, and that they were sending it into the lab and would call me.

Today they called and said that it looked like E. coli but that they weren’t sure if it was contaminated somehow and now tomorrow i am going back.
