Can i be pregnant and get a false negative results ?

Low possibility: Repeat test will help increase the sensitivity of the test

Yes, you can.: Almost all the preg tests sold in the market report efficacy close to 99%. The trick is however, depends on when the tests are done. There is a higher false negative rate if performed before the time of the missed cycle. Most of the pregnancy tests should be positive one week after a missed cycle. Always check the boxes to find out how sensitive they are.
