About 6 months or so ago I got an iPhone. Its a wonderful thing, but now I have the app to track my periods and they have been a different length each month. They range from 23 to 29 days and anything in between. I don't know how long this has been going on- before I never paid much attention, my period just came when it came! And we were lucky not to have much trouble conceiving, so I didn't spend much time thinking about my cycle length then either.

So does anyone know if cycle lengths that vary so much each time are actually a concern, or if this is just a normal variation?

Thank you!
