You're 16, you're not married, you have no insurance, you have abnormal vaginal bleeding, you can't go to a physician...and you believe you're prepared to "be a mom"?
Take a step back, take a deep breath and put things in perspective. You need to get this abnormal bleeding looked into medically first. Is there a Planned Parenthood Organization where you live? They offer lower cost reproductive services and don't require that someone has insurance.
