My last period started February 20th. Now is march 26th and I haven't gotten my period. Could I be pregnant? I know February was a short month and might mess up the cycle date??

if you have had sex during that period, you very well could be pregnant. Go to the dollar store and pick up a pregnancy test. Test in the morning as it will be more accurate. Keep having unprotected sex and inevitably you will get pregnant. It's only a matter of time.
