My LMP was april 3rd....I was expecting my period on May 3rd since I have a 30-31 day cycle...I didn't start bleeding at all until May 16th(over a week late), and when i did it was spotting for a day then light bleeding for 2 then spotting on the 4th last day...normally my period is 5 days long, and heavy for 3 of hte 5 days..this was quite different, so I'm just wondering, what are the chances that I might be pregnant?
