The first day of my last period was on Friday, May 20th. I have a regular 28 day cycle and according to an ovulation calculator on babycenter.ca, I would be most fertile from Tuesday, May 31st until Sunday, June 5th. My boyfriend and I had unprotected sex on Sunday, May 29th, very early in the morning (still dark outside). Is there a chance I could be pregnant even though I wasn't due to be fertile for another couple of days? Please help! I want so bad to be pregnant and the waiting is killing me because it's still too soon to take a pregnancy test!
