Sexual Relationships 
Sexual Health 
It happened. You had unprotected (or even protected) sex, and now your period is a few days late. You automatically panic and the question crosses your mind: Am I Pregnant? Every little stomach twinge or food craving is interpreted as a sign of pregnancy. The worry consumes you and its all you can think of. The good news? You are not alone! Since all methods of contraception are not 100% fail-safe, almost all sexually active women have experienced (or will experience) a pregnancy scare at some point in their life.
I created this myTake in response to the number of teens and young women who worry they may be pregnant...For example: 16 and Pregnant? Not me, please!, Could I maybe be pregnant?, and, Am I pregnant? What do I do?. But before you totally freak out, here are some basic facts you should know that may help ease your mind and answer that burning question.
Disclaimer: Although all methods of contraception are not 100% fail-safe, please be smart and always use some form of protection! Techniques such as Withdrawal or Pull-Out Method are by no means effective methods of preventing pregnancy. Find out what method of birth control is right for you here.
Ovulation: The Fertile Window
It is important to know your cycle. You are most likely to get pregnant around your time of ovulation (When an egg is released from your ovaries). In an average 28-day cycle, the fertile window is approximately 5-6 days. This fertile window occurs 10 -17 days after the first day of your last period (day #1 of the ovulation cycle) with days 13 and 14 being the days you are most likely to conceive. This means that if you had sex during this time-period, you are at the greatest risk of getting pregnant.
It is important to remember that although an egg only lasts 24 hours after ovulations, sperm can live up to 5 days in a woman's body, so if you have sex right after your period, you are approaching your fertile window.
Not sure when you ovulate? The ovulation cycle can differ from woman to woman, and can be anywhere from 21 to 35 days. You can use an ovulation calculator to help determine your most fertile days. Note: this is only an estimation. You should not use this tool to prevent pregnancy.
Reasons For Your Late Period, Besides Pregnancy
So, if you aren't pregnant, what else could cause a late (or missed) period? There can be multiple reasons for this, including extreme stress, hormone fluctuations, diet and weight changes, as well as certain medical conditions.
Stress
Never underestimate the power of stress. A stressful event, such as a breakup, a big move to a new city, or a death in the family are just some of the things that can disrupt the female reproductive cycle. Stress can cause your period to be late, irregular, or missed all together (a condition called secondary amenorrhea).
Hormone fluctuations
Your menstrual cycle is controlled by hormones, therefore, a fluctuation or imbalance of these hormones can irregular periods or flow. The most common culprit of a missed or irregular period is low Estrogen levels.
Diet & weight changes
Diets, such as high-fibre diets and diets that are too low in fats, have been shown to influence a woman's menstrual cycle. Likewise, some foods, such as excessive amounts of caffeine and alcohol can also cause irregular or missed periods. Rapid weight gain or weight loss may also prevent your period from occurring, by producing too much or too little estrogen.
Medical conditions
Missed or irregular periods can also be a sign of certain menstrual disorders such as Polycystic Ovary Syndrome (PCOS) and Endometriosis. That is why it is important to keep track of your menstrual cycles and discuss any irregularities with your doctor.
When in Doubt, Take a Pregnancy Test!
Sometimes not knowing can be the biggest worry, therefore, taking a pregnancy test can help ease your mind.
Although some tests can be taken earlier, it is best to wait and take the test until a week after your missed period for the most accurate results. As there are many different brands of pregnancy tests, always be sure to follow the instructions on the box.
