Hi All, I have 3 boys, have tried Shettles theory. Even finishing bd 4 days before o. I am a vegetarian, very low body fat, cardio for more than an hour 5x a wk. Recently tested ph, mine never going higher than 4.5 but my dh is 12/14!! Have used Genesis for pgd and always had a very low amount of girls to put back. I have then amazed Genesis 3 times by m/c at 6 wks when they believed that things were 1oo% perfect. Do you think that there is anything else that I can do?
