Planned Parenthood is a low income medical clinic. They are for people who can not afford their own medical coverage. It is for Women or Men. Birth control is obtainable. As are check ups as any other clinic would do. You just have to meet the criteria of low income in your state.
Regular spotting is normal. Especially for a girl who is not used to ***. If the bleeding occurs for more than 3 days and it is not a regular menstrual cycle. She would need to see a doctor.
It is impossible to know if the girl is pregnant only a couple days after intercourse. It takes a full menstrual cycle to determine this. In some cases a girl can get her last period and still be pregnant.
Not all birth control is 100% effective. You will get better results combining two methods. Like the pill and a condom.
Please next time ask a doctor about these issues. The internet is no place to turn on health questions
