Im very emotional and my back lower hurts, and when i sit or lay down certin ways its very very uncomfortable it never use to bother me but now it does and i get hot/cold flashs! I did take a HPT but it came back negative did i take one to early and Im a very small girl Im only 5 0 and weights about 90 pounds so what do you think I should do? my body has never felt like this before!! please help
