I am 19 years old I am 170 pounds and I am 5'3". My last period started on may 20 I felt like I had to pee all day and there was a very small amount of blood later that night the feeling stoped and I had a normal flow that lasted its normal amount of time now today I am feeling the same like I need to urinate really badly but very little is coming out there is a small trace of blood. Its a bit early for my period and I have never had this feeling before. I am sexually active I use condoms but I am not on birth control. Can someone tell me what this is I am worried its UTI I dont have health insurance and I dont want to see a doctor unless its serious.
