How to be prepared for my period?

Okay, so I track my period with this app on my iPhone. I'm suppose to get my 3rd period, but you know, they can be irregular. I'm suppose to go to school tomorrow & my period is due (what great timing.lol.)
Any ideas on how to be prepared just in case I get it? :/

How to get my money back from apple?

I sent myself a gift on my iPhone worth $10 so I can purchase some apps. I went to my email so I can see if I had to get a code to redeem the money. I did just that and it turns out my email I had hooked up with iTunes was deactivated due to inactivity. I reactivated my email and I had no messages at all. Not even from ages ago. So did I just waste $10 on nothing? Or is there a way to get my money back or have them resend the email? Please let me know. I know it's just $10, but I practically just threw it away.

Added (1). Took your advice and there's no purchased items in my history. I took a look at my bank statement and it's there. This is very aggravating.

My Playlists for my iPhone aren't working?

I have these playlists on my iPhone that are pre-made so they can't be deleted and I can't manually add any songs to them. They are like "Top 25 most played" and "Recently Played" and stuff like that, but there are no songs on any of them. I've tried finding a setting for it or something that turns it on and off but I can't and I'm pretty OCD about my music being organized so having these empty playlists crowding my phone kinda bugs me… If you can help then Thanks A TON!

Why is my other section so large?

Here is a screenshot of my iphone 5 storage. As you can see, the "other" section takes just about 40% of all of my space. Which stinks because I barely have space for anything else. Can anyone tell me why this could be so large? Or what I could to reduce this?

Iphone won't receive texts/calls?

I can send texts and go on internet tho. If somone tries to call me it goes right to voicemail. I have tried restarting it and also turning it off and on. I also tried reseting the network and nothing worked.

Why isn't my network connection working?

I try to look for a sharing connection on my laptop but nothing shows.

The whole house has Wi-Fi, my Xbox and phone find the network but nothing shows on my laptop. Why?

I get 2 bars of Wi-Fi on my iPhone and 3 bars of Wi-Fi on my Xbox and nothing on my laptop not even a network.

Please and thank you.

Iphone 5 screen replacement

So I currently dropped my iphone 5 and it cracked! However it's not a huge crack, and sometimes you don't notice it. But nothing else is cracked besides the screen. I don't believe the LCD screen or anything of sort is cracked. I don't have AppleCare. I know the price for fixing this is very expensive, and I just don't have 200-300 dollars to spend on this. So is there a d-I-y kit for only the screen, or can companies replace just the screen, and not everything else to make it more affordable. The reason being, is because I would like to sell the phone back for some money when the contracts up, so I don't want any problems!

How much could I sell my iPhone 3GS for? - 1

I have a black, 32 gb iPhone 3GS that I need to rid myself of. It just got a new screen, and it's in pretty good condition, with headphones, a charger, and two cases (one that you can charge and then plug into your phone on the go for extended battery life).It's locked to Telus, but I have a friend who knows how to unlock phones so that's not a problem.
I live in Vancouver, BC, and I was just wondering how much could I sell it for on Craigslist?
