Hello. I had sex one day after my period had completely stopped and my boyfriend came inside me. We are both ready for a baby and want one so I'm really hoping I am pregnant. I had sex on 9.21 and today is 9.28 my next period is due 10.17 can it be likely that I'm pregnant?

Possible... but not incredibly likely. You'd have to know when you ACTUALLY ovulate and that takes a Basal temp chart taken daily for at least a month to find out when you actual ovulation is. THen you know when your most fertile days really are. WIith out that you are just guessing.
