Neg pregn test : At 16 weeks you should look pregnant meaning your stomach should be protruding -is it? There are causes of negative HCG see below http://www.medscape.com/viewarticle/778183_3 If you are missing your period check thyroid , check prolactin and get an ultrasound to check for ovarian cysts and polycystic ovary syndrome
