So I am 19 years old and in a serious relationship with my 21 year old boyfriend of one year. We had sex for the FIRST time about 3 weeks ago, and were dumb enough to not use protection. However, he pulled out, it really didn't last long, I wasn't ovulating, AND I had my period as regular. But I'm having weird brown discharge and strange pains. Could I be pregnant even though I had a normal period or am I just paranoid? I'm so embarrassed to go to the store and buy a test. And if I do, I don't know where to take it. I can't bring it home and risk my parents finding it in the garbage. What if someone I know sees me buying it?
