Im so lost when it comes to charting cause we never done that before.. we just let natural take its course.. been doing that for 9 yrs then got prego then lost a angel baby on dec 22.09

So should i start charting ? this time around?
Honestly im dumbfounded when it comes to this
cause i have no clue what im doing.. or even know how to even start charting..

any help would be appreicated
Thanks..
