First of all, BREATHE, BREATHE, BREATHE. And now for the longest answer in history...
According to the most widely circulated literature, an average woman's cycle length is "generally" 28 days. Different things happen in phases during these 28 days. So very basically, here's what happens:
Days 1-4: Menstrual phase -- This is what everyone calls the "period"
Days 5-13: Proliferative phase -- The lining of the uterus grows
Days 13-16: Ovulatory phase -- Ovulation occurs
Days 17-28: Luteal phase -- If the egg was fertilized, then it implants into the wall of the uterus. If not, the body gets ready to have a "period"
So generally... for a textbook female... the time to get pregnant is about 2 weeks-ish before the mentrual phase (period) begins.
That said, I HAVE NO IDEA WHO THIS TEXTBOOK WOMAN IS!!! I don't know a woman with a 28-day cycle. Most women I know have periods that last about a week. Every woman is different. My cycle is 32 days, and I ovulate about 4 days before the start of my cycle so my luteal phase is super short, possibly too short to allow for implantation if I ever wanted to conceive. Our cycles can be thrown off by stress, diet, dieting, body fat percentage, prescription medications, or being around other women. It's well documented that women in dorms or other close quarters experience their cycles altering and synching in some ways.
So, there isn't really an answer to your question. It depends on her body, but it's not likely that the "textbook" woman would be pregnant. Many women experience breast tenderness as a symptom of PMS. That said, unless you're monitoring hormones, or cervical position, or vaginal fluid viscosity, or basal body temperature, etc, you have no idea what you're dealing with... so it's best to assume that no day is safe.
What this means for you today is that you have to wait and see what an early detection test says and/or wait for her period to start.
What this means for you in the future is that you've got to get smarter about being sexually active.
You should NEVER do that whole head teasing thing you did without a condom because of the risk of pregnancy and getting an STD. That's something my husband and I get to do because I have an IUD, we're monogamous, STD-free, have a stable relationship, are self-sufficient, have money saved for a surprise baby and have a home that belongs to us to put the kid in. We have taken responsible steps to get to do that. You have not. NEVER do this. It's too risky for you. I watched the video you made. You are so talented. Having a baby before you're prepared could wreck your bright future and make your tense home situation far, far worse.
That said... A condom is never enough. We just had one of my pill-hating friends, her husband, and their two "condom only" sons over for the evening. Condoms can break or slip off. Sperm are tiny cells. A tear too small to be seen is all it takes.
You need to make sure at least two methods of birth control are being used at the same time. SHE needs to be on the pill, the ring, a diaphragm, etc or something stronger than an "I hope I don't get pregnant" wish. YOU need to always wear a condom and use another spermicide (one that is compatible with the condom material) at the least. I bet you've seen Rob post this link at least 10 times this month alone (http://www.plannedparenthood.org/info-for-teens/pregnancy/am-pregnant-33831.asp). Understand this page.
Chances are good that any woman you're with has no idea when she's ovulating because --- for reasons I just still can't understand --- most sexually active girls/women don't know anything about how their bodies work. So, if she doesn't know, you have no hope of knowing. You need to make sure you always have condoms and an additional spermicide.
Remember these feelings of panic and fear, and take greater steps to inform and protect yourself in the future. If you can't handle the consequences of a behavior, then that's a good indication that you shouldn't be doing it. There's nothing wrong with waiting until you're older. I was in my 20s when I started having sex. Darn it, I know I'm getting older because I just don't think "young people" understand how serious this all is. Please don't become a statistic. I was reared by a teen mom (she actually was raped...). I'm telling you, my mother struggled, suffered, sacrificed and lost her own childhood so that I wouldn't be limited by my birth circumstances.
You don't want to lose your childhood, so please be more careful going forward.

Thank you so much. This is actually the only first long answer I stuck with reading but I got lost in most of it. Can you please explain the whole 28 day cycle thing again? But in simple terms? Thank you ):
Basically, if she's like the medical textbook model woman then most likely the time she could have become pregnant would have been 2-1.5 weeks before Jan 27. Her period could be late because she's so stressed out about maybe being pregnant. Sore breasts could be from PMS.
If she's not like the medical textbook model woman then you can't know if she's pregnant until her period starts or she tests positive.
All you can do now is breathe, wait for either of those signs (positive test or period), and take steps to avoid this in the future.
You should also learn about Plan B emergency contraception which can be used up to 72 hours after intercourse. You should always have a plan and money to get it if needed.

Today, she did get a pregnancy test. She is just waiting on more privacy(her mom going out) before she tests herself. I am so scared! I don't want to be a dad at the age of 15. I don't want her to be a mom either ):
I'm glad this worked out. I hope you can sleep tonight. :-)
