HELPPPPP!!!!!!

Hello all you beautiful mums!

Please help! I had my last period on Jan.27th or 28th (thats the beginning date) me and the hubby had sex on Feb 6th and he did the deed inside (sorry TMI) Im seriously not sure when i usually ovulate or what my cycle ranges from. So basically i had sex the 11th day of my cycle..what are the chances of me being pregnant or getting pregnant?! I hear sperm can live up to 5 to 7 days?
