Well my last period ended on the 10th of Jan 2010, around that date, and I had unprotected sex on the 17 of Jan. 2010. He said he did not pull out in time, I do not know exactly how much he got in me, but I am worried. I took a pregnancy test the following Saturday which was 6 days after the unprotected sex. My sister's friend said a test could be accurate then, and it was a Clear Blue brand and it said I was not pregnant. But I am still thinking about it, I know it has to be a possibility still, so I am wandering my period should start on the 6 or 7th of Feb 2010 (as counting the 27-28 days later), and I started to have some brown discharge, but when I wipe it's like a reddish pink. I have had no symptoms of pregnancy. So I am wandering is there a chance I am pregnant?
