I've just started my period, and I'm 12 years old. I'm feeling scared. What does this signify?
It generally indicates that your period is arriving on schedule. Menstruation can begin as early as age 10 and as late as age 15. Starting your period at 12 years old is right around the average age for girls to begin their menstrual cycles. So, stay calm and get comfortable. There’s no need to worry; you haven’t done anything wrong. Your body is just shedding the monthly buildup of the uterine lining. It's a significant responsibility and a privilege, as you have been chosen.
Worried about what to expect? Naturally! And That's On Period! is here to guide young girls through some of the symptoms, physical responses, and hormonal changes. Your first period often comes as a surprise. That's okay, let's be prepared for when it happens. A first period kit is one of the best ways to manage an unexpected period. It should include a sanitary napkin, travel soap, washcloth, panties, and a pair of pants (we suggest sturdy leggings, as they're easier to pack and travel with). Sound good? Great, we have a plan.
Most importantly, embrace period positivity. Take pride in experiencing this life-changing event and recognize the importance of being confident about something only you can manage for yourself. You're stepping into a significant phase, but you're still young, so it's important to seek support to feel positive, strong, and understand there's nothing to be ashamed of. Let's explain what occurs when your body is menstruating. We've already discussed that the uterus lining is shedding. This indicates that no eggs were fertilized during your cycle. Note: the start of your period does mean that if an egg is fertilized, pregnancy will likely occur. Expect your period to last between 2-7 days. Your first period may appear brownish, which is normal. The blood might also be red, and that's normal too. If you have concerns and seek medical advice, please contact your primary physician or local free clinic.
Get used to saying "I am on my period," "My period just started," or "I'm bleeding." It's perfectly normal to go through your period; it's a sign of health and development as a young woman. You're in control and prepared to handle the 2-7 days of bleeding, which indicates that your body is changing and maturing; you're growing. Growth is always positive. Appreciate growth. Experience growth. Embrace growth.
Emotions will be intense. During this period, it's important to have support and to communicate with the adults in your life about what you need to feel secure, comfortable, and improve your well-being.
