Look I'm having all the symptoms I'm having headaches, lower back pain, nausea, night sweats, sore and leaking breasts, lightheadness, hot flashes and increasing size of my stomach that is hard and round and I look like I did when I was 51/2 to 6 months along with my other 3 kids. What should I do? I know I'm pregnant--there's no ifs and or buts about it. I'm also feeling moving and kicking. Can you tell me what I should do, since the blood and the urine tests are coming out negative.

You can ask your doctor to do an ultrasound.

He doesn't think I am cause of the tests not coming back positive but he sees I'm showing big time

If a blood test is coming back negative it would be doubtful you're pregnant. But if a doctor can see you are visibly "showing" then you would definitely need further diagnostics to figure out what is going on.

When was your last period?

Hasn't your doctor done an internal exam? If you're allegedly that far along, you should have had a sonagram and be taking prenatal vitamins and having monthly internal exams

Even if the tests are negative, clearly you're having issues that could be hormonal or even digestive such as constipation. An ultrasound would be beneficial. Maybe you should try your family physician if your gyn isn't being very helpful.
