pregnant? My husband and I quit using birth control 7 or so months ago. I was due to start my period on September 5th and it didn't come. I took a test this morning and it came back negative. When I concieved my son nearly three years ago the test instantly popped up positive. I was wondering if anyone knows of any reason other than pregnancy that would cause my period to be late, or if it is possible that I am pregnant and it's not showing up yet?
