I am really sorry nikki, but you really are wrong. This is my one area that I am very familiar with. I have 4 children, and I am 38 years old. My husband and I attended a family planning clicic for all of our 4 children and they worked with us to figure my ovulation period which was only 2 days, anytime outside of this was completely impossible. If the egg is not there to be fertilised then there will be no pregnancy. I also have a lot of information from my gynocologyst on this subject that I would be happy to post for you if you are still not satisfied.
I hope this has helped a little bit, cindy
