Yes, you can get pregnant right after your period. You are actually starting to move into your fertility window. On a typical cycle that occurs every 28 to 30 days, the fertility window is usually between Day 11 and Day 21. As noted above sperm can live 2, 3 and up to 5 days. If your period (bleeding time) last for 5 to 7 days, and you have sex right after that, you are approaching your fertility window.

If you stop bleeding on Day 6, have sex on Day 7, and ovulate on Day 11. It is possible that the sperm from Day 6 will be waiting in your fallopian tubes for conception. Of course, your chances of conceiving right after your period increase with each day after your bleeding has stopped. If you are trying to conceive this is a good time to start having sex. Increase your chances of conception by having sex every other day for the next 14 days.
