Help! Confused?!

Last month on Feburary 2nd, I had a normal 5 day period lasting until Feburary 6th. On Feburary 10th, my SO and I had protected sex but, while in the middle of sex he pulled out & ejaculated a little into the condom. After ejaculating into the condom, he proceeded to change the condom and start fresh, which lead to him ejaculating once more. It is now March 11th and my period was set to come on the 6th. Could I be pregnant if while he was changing the condom sperm may have came in contact with the new condom? Should I take a hpt? My cycle lasts 31 days.
