I am 19 am not on birth control,but me and my boyfriend are decided whatever happens happens. I'm just curious what is wrong I have orange to yellow discharge and my lower abdomen hurts.Its not an infection because doesn't smell or burn or anything like that.I went to the doctor and they did blood and urine tests and they did a pelvic exam.They are sending me to get a ultrasound tomorrow they said it could be a few different things. Any ideas?
