according to this app and a few others, I am ovulating and smack dab in the middle of my cycles. however, I have taken several ovulation tests and they show "no LH surge" huh?? How is that possible? Is something wrong with me? I know i have to go to the Dr, but just seeing if anyone had any insight?
