A nice, long, big one. We can't ever say what a risk was in numbers for one single incident, because fertility varies both from person-to-person and from day-to-day. I also know it can be tempting to put off taking that test. For those reasons, we strongly suggest NOT going to CPCs for pregnancy options counseling, since they are both nonsupportive of all choices, but also often do not give accurate information about the choices they do support. Scary things feel a lot scarier while hyperventilating, and adding more stress to an already stressful situation only assures you'll feel worse. Maybe you're still scared because you aren't using birth control when and how you should be, or feel unable to deal with any risk of pregnancy at all, even a tiny one. The longer we wait to test, the more limited our choices with pregnancy become. Heck, many people who simply have a uterus , and even people who don't have one but have been within 20 miles of one, have experienced fear about potential pregnancy. Talk to someone first who you trust and know will treat you with kindness and respect. Are you pregnant and need to tell your parents about it? No matter how you feel about it, pregnancy is big and something no one should have to be alone in. Have you been or are you using a reliable method of birth control? Vaginal intercourse, where a penis is inside a vagina, is the kind of sex that MOST commonly results in a pregnancy. If you feel you may do yourself harm, please get immediate care -- like calling a suicide hotline or going to your local emergency room -- or tell someone you know will help keep you safe. That doesn't mean you don't get to have or sensitively voice your own wants, needs and feelings. Sometimes unintended pregnancy is so unwanted and so scary that people will be tempted to harm themselves in some way. Most often, the very first symptom of early pregnancy is a missed period.
