How long ago did you take the last pregnancy test? It may be that your cycle is just off, it may be due to pregnancy, but it could have occurred recently and testing is not picking it up yet.

If you haven't tested recently, you could try another test or you could see your doctor for a test in office. Otherwise, wait and see if you miss a second month and test at that time.

First. Are you taking your home pregnancy tests the right way. Meaning first thing in the AM, right after you wake up, the first time you pee that day? If not you are doing it wrong.

Its unusual to test negative for two months but not impossible. If you are testing correctly, perhaps its time to go get a blood based Pregnancy test at your doctors.

If THAT results in a negative... then there is something else going on that caused you to miss your periods (that happens sometimes).
