My name is Mireille I go my period August 8 2001. I have a normal 28 day cycle I should have gotten my period on Sept 4, 2001 it is now the sept 9th and there is still no sign of my period a couple of days before I was supposed to get my period I had a yeast infection and before the yeast infection I felt really dizzy for about 1 minute I sat down and the feeling went away. I tried to take a home test and it was blank not even the test line appeared. I went to a clinic and had a test done around 5:00pm I could not urinate enough to cover the bottom of the cup they still did the test and it came up negative. Should I take their word for it or do you think there is still a chance I am pregnant. I have also been urinating like crazy I almost went on myself one night. I am hoping maybe it is a bladder infection but I never heard of a bladder infection that makes your period late. please respond asap.
