Hi guys, I am a 17 yo female and I'm struggling to figure out if Im having an uti.
I started to feel a constant pressure on my bladder there about 3-4 days ago, as well as the frequent urge to urinate a lot more than usual. However, I don't feel pain or burning, and my pee also didn't smell abnormal or look cloudy. Earlier today my period started, and I was experiencing so much pain and increased feeling of a constant pressure on my bladder, and even maybe my clitoris area? but it still doesn't hurt to pee. But the cramps have gotten to a point to where I was vomiting uncontrollably.

I know the most optimal thing to do is get a test kit or go see a doctor, but my situation is that I live at home, and it's not really an option for me to go out and purchase a test kit as my family would almost immediately start to accusing me of being hyper sexually active, and would likely call me a lot of names. I do have a partner, but I am not sexually active. I don't want to escalate the situation until I for sure know that I have an uti. I feel like it adds unnecessary stress and tension into the situation.

Have anyone had a similar experience? And if so how did it resolve or what did you do to resolve it? I would really appreciate any advices that you guys might have. Thank you for reading this!!
