If you are pregnant you are in for a lifetime commitment to your child. Pregancy is no walk in the park. I recently found out that I am pregnant I have been sick for days. The only advantage that I have is that I am married and my life is stable. I am advising you to stop having sex and to focus on postive things in your life like finishing high school and perhaps furthing your education in college.
Unprotected sex is just like a death certificate.
You are signing your life over. If you must have sex please protect yourself, more and more young people are dying from aids. You should also have your self tested for any type of sexual transmitted diseases. You should go down to your local library and do some research on your body and the changes that take place in your body during your menstrual cycle. This is something that you should know.
