Any kid has the right to see a doc by themselves. If they have the money to pay for it out of pocket then I imagine they wouldn't even have to tell anyone. I would think that a teen is more able to do this than any other age though. The doc always asks my grand kids if they want me to stay or go.
As for being a week pregnant. Really? I didn't know you could tell that soon. SO I'm confused.
If she's just a week pregnant then she would be due around graduation.
If she is in danger, truly at risk from her parents rath then she needs to find a family she can stay with and that would support her in going to an alternative school where she can graduate on time. She absolutely needs to finish high school. She will have that hanging over her head her whole life and it's just not worth it to drop out due to being pregnant.
As for her parents. Once she is 18 they can't tell her if she can keep the baby or not. They won't have that right anymore. \
If she wants to go to court and be emancipated she can also do that. In her situation I think that might be the thing to discuss with an attorney.
Being emancipated means her parents wouldn't be responsible for giving her anything, not food, shelter, car, phone, gasoline, insurance, nothing. She would be an adult out living on her own.
If there are shelters in the area for pregnant women or teens or even families they could be places of refuge for her.
She can apply for food stamps, WIC to get food for herself now and after the baby is born she can get formula then when it's a year old she can get other foods. She can get child care assistance so she can work full time or go on to college. There isn't anything she won't be able to do that a normal person her age can do.
Many single women go to college while being a mom too. They put their kids in child care and go to school instead of a job. They use their financial aid to pay their bills and buy the things they need. Again, there isn't anything she isn't capable or able to do just because she will have a child.
