My husband and I had completely unprotected sex on the 25th. I have never really charted or followed my ovulation dates. I searched on the internet for an ovulation calender and found that the 25th and 26th were my most fertile days. I have a 5 month old baby, but am not completely opossed to having another soon. I'm not sure if I want another one right away, but if it happens I am fine with it. My question is, what are my chances of getting pregnant by having sex on my most fertile day?
