Hi, I had unprotected sex 6 days before my mentral cyle was due. The first day of my last cycle was May 6th, 2003. Today is June 9th, 2003 and my period still has not come. I took a pregnancy test this morning but it came back negative. Is it possible that I got pregnant in the last 6 days, or did my cycle got messed up because of having unprotected sex. Also, should I take another pregnancy test? Thanks for your help, Dee.
