Hello! I'm getting ready to try for baby number four. Just stopped by BC which I have been on for about a year now and I know that when I am not on BC my cycle is all over the place. Anywhere from 26 days up to 40. It ranges significantly from month to month, which can be a pain when trying to figure out which days I am ovulating. I've been hearing about charting for years but don't actually know what it is or how it helps you get pregnant. Thanks!
