2 month without a period...i took a pregnancy they are coming up negative...could i still be pregnant?

Very unlikely: Pregnancy tests are accurate and reliable, and although no test is 100%, pregnancy tests are close. If you have more than one negative pregnancy test then it is very unlikely that you are pregnant. It is not unusual for a woman to miss 1-2 periods once in awhile. Any type of stress, physical or emotional, can cause missed periods. Sometimes there is no apparent reason.
