I am 19 years old and I think I'm pregnant. My period was supposed to come on this week, yesterday to be exact and I don't feel any of my usual symptoms. When I looked up "what is the time period that you are most fertile", it was 12-14 days after the first day of your most recent period. Well I had my last period on the night of the 24 of October, morning of the 25; and I had sex on my birthday which was November 5. Looking back at the calendar, that is exactly  12 days. I'm so nervous to even take a pregnancy test because I don't want to face the truth. I am a second year student in college and I know that I couldn't provide for a baby. I know I was grown enough to make the decision to have sex but I don't know what I would do if I was pregnant. Please, any advice would be greatly appreciated
