I seem to have misplaced my period. It was last seen on December fourth, and has been AWOL since then. I am sexually active and not on HBC, but we are fairly strict with our condom use and safe sex practices. I took a pregnancy test one week ago, and it was negative. I haven't noticed any of the secondary symptoms of pregnancy. This missing period not abnormal for me; my cycle is very irregular, and can range from 30 days to over two months. The fact that I am now going on three months without bleeding is starting to worry me, however. What the hell could be going on? Should I schedule a gynecologist's appointment?
