what is going on??

Jerica
A few months ago I went to the doctor and get a negative pregnancy blood test. I haven't had sex since and now there is movement in my stomach. I can faintly feel it with my hand after eating certain things. I've had very faint periods so I don't know what's going on. Every time I call my doctor about it she says it's in my head! She says the reason my stomach started getting hard is because I need to lose weight. But I have been losing weight that's the problem my stomach is still huge! Any tips? I'm probably just going insane but it would be nice to know if that's the case.
