Fertility tracking question

[Nic_ann_robs]

Hi! I am loving the fertility tracker. It works much better than any other I’ve used. I would like to make one suggestion. When I tap to update my period for the current month, previous months change based on predicted trends. I have been making note of my own ovulation cramps in relation to how accurate the apps prediction is. So far it’s either been right on the money or just a day off. But when everything shifts, I lose that personal data because your predicted ovulation day moves away from my note. Previous months should lock as they pass, with future months adjusting for trends.

Hello @Nic_ann_robs and welcome to the Help forums.  You pointed out an interesting feature of the fertility tracker.  When users have suggestions like this, the thing to do is check out the Feature Suggestion forum.  A request for this might exist or you might need to start one. 

Also, I am going to move your post to the Female Health Tracking forum.  It sounds like this issue applies to female health tracking, not just the iOS app.  A thread might be on that forum already.

BTW, I consider your observation a bug to be fixed.  Old data should not be changed.

@LZeeW Thank you for the info and for moving the post! 

Would I treat a bug similar to a feature suggestion?

@Nic_ann_robs   True "bugs" are usually brought to the attention of the moderators who bring it to the attention of the engineers.  I would go the feature suggestion route and emphasize that it is something that needs to be fixed.

Welcome to the Community Forums @Nic_ann_robs! Thanks for bringing this up. I was wondering if you've tried to turn off predictions and edit the Period and Cycle length? Then you can turn back on the predictions.

Your estimated fertile window automatically adjusts based on the menstrual cycle data you enter. You can’t edit fertile windows. To turn off fertility predictions, see How do I edit my female health settings? 

You can edit the average cycle length and period length you provided during setup; however, these settings only affect your initial predictions. Keep the following in mind:

• Edit your average cycle length to adjust the length of your entire cycle. If fertility predictions are on, the predictions for your fertile window and ovulation day adjust based on the length of your cycle. For more information, see our blog post Ovulation, Fertility, and Pregnancy: What It Really Takes To Make a Baby. 

Thanks for your help and for moving the post @LZeeW!
