Hi. I'm 18 years old and had sex with one guy. I ended up getting a UTI. Of course me not knowing what a UTI was I ignored it. Bad idea I ended up with a bad kidney infection! I went to the doctors and they took my blood and all and I got meds. 3 days ago I shaved my vaginal area and got little redish bumps. I had razor bumps before but it was always on the top. These are on the side of my vag......they are sore doesn't hurt just sore and kind of red. It can't be a STD or something right? I mean wouldnt the hospital see if I had a STD in my blood or pee if I had one?...... I'm scared and nervous. Can someone help me please....
