How to use the fertility tab on the Pink Pad app for iPhone?

On the Pink Pad App for iPhones, there's a Fertility tab, and there's a lot of options and it's very complicated and I'm not sure what some things mean. Could someone explain the following:

(These are the selections and the available answers it gives you to choose from)
Ovulated today: (you just click the button if you have I guess?)
Cervical Mucus & Observations: Dry - Sticky - Creamy - Watery - Egg White
Position: Low - Medium - High
Firmness: Firm - Medium - Soft
Opening: Closed - Medium - Open
Ovulation Kit: Negative - Positive
Fertility Kit: Low - High - Peak
Ferning: None - Partial - Full

So if someone could explain what these options and selections mean I would appreciate it!

Here is the web site for the fertility app.

  • Why is my new tab page on iPhone 4S in Chinese? I just updated my iPhone 4S to ios7 and when I'm on safari and click a new tab the "home" page shows sites like Wikipedia and iCloud but the labels are in Chinese for some reason? I don't speak Chinese I've never had my phone in Chinese at all so I don't know why this happened and does anyone know how to fix it? The phone is already set to English but still Safari is Chinese.
  • What is the virgin mobile super-tab? So I'm 13 and really want a phone, an iPhone 4 specifically. My parent are not keen on the idea of signing for me for a 3 year contract. So then I was browsing and saw an option for this supertab thing. What is it? How does it work? How much would you have to pay monthly (like for texting etc)? I make about 20-40 bucks a week for babysitting, would it be enough to pay if I got an pretty good plan? How am I a spoiled brat?

  • My iPhone 5 won't play music samples from iTunes when I tab out? I just got my iPhone 5 today, and my 4S never did this. I listened to a sample of a song in iTunes, and tabbed out, but the music stopped once I went to the home screen or another app. Why did it do this? I thought the iPhone 5 was supposed to be an improvement. Does anyone else have this problem? Is there any way I could fix it? Your help is so appreciated!
