Com'on Glow. I already ovulated! I got positive opks on cycle day 12 and 13. They along with tempts were logged and now my bbt has confirmed ovulation on cycle day 12. but how come you still don't change your prediction on my fertile week? According to glow, my fertile week starts April 1st, you must be kidding..
