some do take it from day 14 (expected date of conception) found it funny when going for tests my nurse wanted blood from day 21, i said wots the point when u ovulate on day 14, she disagreed, said 14 days from date of end of period based on a period of 7 days. so i thought i had been doing it all wrong lol but everywhere u look up says day 14 fpr ovulation. who knows? any ways dont feel sorry for me. I think it was for the best, as he is turning into such a prick. I've had my children, was only trying for him and the minute i found out he wanted to go out drinking , leading the single life. Sad as it sounds but lucky escape i believe.
