Traylee- you might find that you are ovulating at a different time to when ff says. I had a 28 day cycle and when I started temping I found out that I was Oing on day 17, not 14 like ff said. Once I added temps to ff the charts made a lot more sense and we were dding on the right days. If I'd been going by day 14 we would have missed it every month. Anyway, once I started temping it took 4 months and I was UTD!!
