You are 17? Well honey, for all tense and purposes you are an adult. Many people dont know this but 17 1/2 years old you can force the state to recognixe you as an adult. Use the recources around you. Start with the white pages. Listen up, the very beginning of the white pages are your government listings. Use them.That's what they are there for. Even if you are not sure. Next, get medical attention. Take your prenatal vitamins. Don't overeat, rather eat like normal but healthy. (i.E. 3 sqare meals a day.)
about the boyfriend. I'm not making any judgement calls. What you need to do is get him to sign the birth certificate. Give the baby his last name and there is a form concerning paternity. Get him to sign it. If he signs this form it prohibits him from contesting paternity in court. If you believe he will never sign it relax. His mother is the key tell her, in the nicest most innocent way that you are going to have her grandchild. Even if she calls you a prostitute who is just trying to trap her son, when it comes the day of the birth, she will make him sign that form because she will have had several months to think ab0out it and she will realize that she won't get to see her grandchild unless she makes good with you.
One more thing. Whatever god you believe in, he loves you and he loves your baby. If you have more questions go ahead and pm me.
