Like all girls that have had a period please tell me where to go for help?

Many places. If you want confidential testing or simply want to establish yourself with an ob/gyn, simply call the nearest office and ask what programs are available for your situation. Most offices offer confidential programs for teens, std checks, free pregnancy testing, or simply education services for most patients. If in school, try asking your school nurse, or better yet, your mom-she might surprise you.
