Hi I'm 21 years old and periods are quite regular (every 29 days) . My period has never skipped a month. I have been sexually active this past month and my period did not show, but I took a home pregnancy test and it came back negative. My last period was April 16 and it is now June 1. The only pregnancy symptoms I have is fatigue and weigt gain, but the test still came back negative. What could this be and I have not been under any stress lately? &nb sp; Concerned Female
