Hi, I'm hoping I could get some advice from someone here... okay, the first day of my last period was 12/25/09, and now its January 27, 2010. I haven't gotten my period yet, but I have been having unprotected sex with my boyfriend. We don't try to conceive, we use the pull out method. Can I be late cause I'm pregnant?? How long should I wait to take a home pregnancy test?? Please help.
