Period tracking module in health app

I was surprised to find out that the “health” app does not include any features for reproductive health such as period, ovulation or libido tracking. I would really like to see a feature like that. It makes a lot of sense and all other period tracking apps I have found are a absolute privacy nightmare. There has been a feature request for it on github but the developer closed it. Now I am not a developer but I know a lot of people could really use a feature like this, so how can I best help make this a reality? Does this feature make as much sense to any one else?
