why bother:
a regular 28 day cycle does NOT mean you have a 14 day lp. If you have a short lp it can be indicative of problems. Charting can point this out and allow you to take care of it ahead of time.
a regular 28 day cycle does NOT mean it will continue to be 28 days... if you know your LP length and O date... you will know if AF is actually late or if you just Oed later for whatever reason. This saves a lot of wondering why you are getting BFNs and AF is 3 days supposedly-late when you are only 6dpo and AF isnt due for a week. Regular cycles in the past does NOT mean they will stay that way and when many women start to TTC (charting or not) amazingly their bodies start to screw up.
Of course, you don't HAVE to chart... but as I said if you suddenly get a totally normal curve ball thrown at you by your body... it saves a lot of wondering when you already know what is going on.
Personally... I charted for months when not TTC (DF was deployed overseas) just because charting out things other than just BBT helped me to understand my body REALLY well... and also was enough to prove that my migraines have nothing to do with my hormones (no matter where in my cycle I was, I was just as likely to get them) but my IBS did (which I then took care of until I got pregnant and it threw me all out of whack again... ugh! LOL)
