Anyone else experience an incorrect ovulation chart? Seems that despite me logging daily and updating my period length, my ovulation cycle stays the same. For example there were a couple times my period lasted 7 days (I know...yikes!) instead of the reg 5 days. Despite adding those days my OC didn't change at all. My physical symptoms indicate that my chart is showing ovulation a week or so earlier than it might be happening for me. I'm not worried about getting pregnant as I have birth control and not having sex currently, but its just annoying I guess lol.
