To get pregnant on a non-ovulating week. Or is it only possible to get pregnant within those 7 days. Yesterday was the last day of my fertile window. And for the last 3 days my boobs have been crazy sore. The only other time in my life that I have had sore boobs was 10 years ago when I was pregnant with my first and only daughter. So I'm starting to think... ok.... maybe it's my time. But then I realize I didn't miss my period last month and I'm currently ovulating so there is no possible way a baby could have stuck... right????
