It was very easy for me and my ex fiance to conceive especially compared to other couples i know of. We had unprotected sex 5-8 times before we realized she was pregnant. The second child it only took once and she took the beforeafter pill and still became pregnant. We still know both cpnception dates of our 2 boys and according to the doctor when doing the sonogram we were right as well so sperm seems to be in very good shape.
