When you
chart, what have you tried? Women
chart the Body temp and sometimes there cervical mucus or even Ovulation Predictor Kits.
If you use the Body Temp method, you need to take your temp every day before you get out of bed, and wright down the numbers, usually if your temp starts to go up that's when your ovulating. If you mark down your temp every day on one of the trackers on this site, you can always ask someone for more specific advice on how to read it once a cycle has passed.
