So, I'm three days late... I have never in my life been late, ever. Not a day, not even a few hours. That's how consistent my cycle is. Now that I'm three days late, I'm wondering (and hoping of course) if there's a chance I'm pregnant... Here's the problem: I've taken three pregnancy tests (one per day since I discovered I was late), and all three came back negative... what does this mean? Have any of you had a late period and had to wait a number of days for a positive reading? How long should I wait before I call my doctor? Opinons appreciated!
