Hi,
I'm sorry that you're in pain. It could mean a lot of things. It could be your uterus stretching as your baby grows inside, so that there's more room. But,it is best if you could get to a doctor and get examined, get on some prenatal vitamins and iron. It is very important not to keep this to yourself, or you could be having major complications and never know it until it is too late. I know that you feel alone and scared about what has happened, but there are a lot of resources for you if you need care. Call, 1-800-395-HELP. It is a confidential helpline for crisis pregnancies. They will put you in touch with someone in your area, and they can assist you in getting to a physician, state assistance for medical coverage, and even have someone go with you to talk to your parents. You need assistance!! At a young age, things from your perspective can be overwhelming if you don't have love and support. Call that number, and talk to the people on the line. Tell them your concerns and fears as well as the fact that you haven't told your parents. Don't be afraid to stand up for your baby, and hopefully your parents will see the love you have for him/her and will want to support you.
We are here to help if you need advice or loving support.
God bless,
