Dog bite while pregnant?

I am 9 weeks and 5 days pregnant. And I got bit by my parents yappy little wiener dog. It took a big chunk of skin and left a mark the size of a susan b anthony coin. That was saturday and I still have the mark from it on tuesday. Well apparently my parents wanted me to keep it hush hush. Cause they yelled at me when I said anything to anyone they heard from. I am so mad, but my dad's trying to blackmail me into not allowing me to see my brother this summer if anyone else finds out. Mind you my brother is only 12 going on 13 years old. And I think that's a crock of ****.
