Less than a week ago I had protected sex with a new partner. Even though we used a condom I have been anxious and worried since. The day after I felt like I had a uti as I get them often thats what my first thought was. But I cant get the knot out of my stomach thinking i may have something. 2 days into the assumed uti my labia are a bit swollen and tender nothing crazy I told myself probably just from the toilet paper so often. No other symptoms but it wont be a week since the sex happend for another two days. Should I get tested to ease my mind and as not to possible infect anyone else. Or am I so nervous I am making these symptoms in my head from anxiety?
