Does anyone have similar experiances or any advice for me? Thank you!

DO you know which blood test was done A quantitative blood test, usually called a beta (hCG) test can detect minimal levels of HCG hormone, and the qualititative measures the exact units of hCG in the blood and will give you a yes or no answer. I am not sure which one he performed, however I am shock that he didn't run further test as providing you with an ultrasound to or a pelvic exam to make for certain you are not pregnant. Are you on any pills, any medications? Stress? Have you recently been taking any birthcontrol? A missed menses can indicate many things.. even hormone imbalance, its hard to give an accurate answer without evaluating your medical history.

If you feel that you are not satisfied with your doctor you can always get a second opinion, or find another doctor.

False positive results are very rare, and typically are due to an very early miscarriage, rather then being a true false positive. I suggest that you talk with your doctor about the results, and see if you can obtain a quantatative blood test. This will answer without doubt whether you are pregnant. This test measures the exact amount of hcg in your system. If there is enough hcg present to suggest pregnancy, the test will be repeated within a few days, to see if the numbers are doubling as they should in a normal healthy pregnancy. Its important to remember that every test measures hcg levels at different strengths. Also, the longer the urine is held in your bladder, the more hcg builds up. That is why they suggest you test with first morning urine, as it has a higher concentration of hcg in your system, from not peeing as often through the night. Qualatative blood tests(the most common blood test to be given for determining pregnancy) is typically more accurate at detecting pregnancy then hpts. However, they are not without error. If your hcg levels still aren't high enough to register on it, it is possible to get a false negative. So, I suggest you talk to your doctor about the mixed results. As it has been a few months since you had your period, it is definitely a good idea to talk to your physician immediately, and figure out what is going on.
