Subject: At what stage of the 28 menstrual cycle is fertilization not possible

Hi,

I've gone through the archives, but cant find anything to really answer my 
question.  What are the chances of fertilization one or two days before or 
after menstruation?  

To my knowledge a female is not fertile and therefore sperm are basically on a 
dead end track if intercourse was to be had at that stage.  Is this true, or is 
there the off-chance that it might happen?  Will the Ovum be on it's way down 
teh fallopian tube at that stage after menstruation and the uterus was merely 
finishing the process of getting rid of all the extra lining?

Thank you for a great service and a stirling job!

Regards
Leonie
