hi my name is rosa,
i've been a little confused lately. I'm 18 years old and I resently started to have sexual intercourse, therefor i'm new in all of this stuff there has been a couple of times when I have the feeling that i'm pregnant, but my question has always been if a pregnancy starts right since the moment you have sex or does it take two to three weeks?

I have asked a couple of people, and none of the people i've asked seem to know the answer. If anybody knows the answer for my question, would you be kind enough to let me know. I would really apriciated. Thank you.
