It has been 2 days since my partner and I had intercourse and my breast are feeling sore, could I be showing signs of pregnancy this early(2 days after I would have concieved)?? I should not get my period for another 13 to 14 days. Or maybe a better question is... how early can you show signs of pregnancy? We would be so excited if I was...

Implantation doesn't even occur for roughly 3 days after intercourse and fertilization. So basically, even if you conceived from that coupling, you would just have a fertilized egg travelling to your uterus at this point. You wouldn't feel any real pregnancy symptoms for a week or two after implantation.
