I dont think you are pregnant.

a blood test would be positive before you even start feeling symptoms. try drinking more water and you might feel better.

I agree with the other ladies. Blood tests are pretty accurate. You should also take other factors into consideration... have you have unprotected sex? Is your period late? If you aren't late yet, i would retest about a week after your expected period. If you are already late, and you keep experiencing these symptoms, I would go back to the doctor and explain your situation to them. Like ernie said you might just need to drink some water, maybe a stomach bug or something. Keep us posted***

Blood test confirms pregnancy rather than "pregnancy symptoms" you could have some sort of virus. Be careful next time if you are worried to be pregnant since you are pretty young.

I completely disagree with the others as far as blood tests. If you're having sex, there's always a chance you could be pregnant.

For 2 weeks I kept getting positive home pregnancy tests and had 2 NEGATIVE blood tests.

A regular doctor doesn't usually know to order a QUANTITIVE S-HCG. Most order a QUALITIVE which doesn't show positive unless you are at least 7-8 weeks along (according to my High-Risk OB). Quantitive measures the EXACT amount of HCG in your blood and can tell you whether you are or aren't. A not-pregnant woman should have an HCG of <4. Anthing higher than 4 will be flagged as HIGH and there will be a list broken down week by week (after conception) in a range of where it should fall.

My OB also said, between a QUALITIVE S-HCG and a home pregnancy test, the home pregnancy test is more trust worthy given the fact that they're cheap and very unlikely to give false positives within the time alotted on the box.

If you still haven't gotten your period, I recomment calling your primary doctor and asking them to fax an order over to your local lab for a QUANTITIVE HCG Blood Test and let them know why.
