Okay Saturday me & my boyfriend decided to do it for the first time . and I made him use protection well we didnt do it for a long time & we stopped . well the next day I went to pee and after I peed it burned for 5 secs and small light drops of blood drop in the toilet and it been like this for 4 days . how can I get rid of the burning and blood ? Is it normal ? Do I have a UTI ? can drinking water and cranberry juice work ?
