Is Pregnancy Possible Through Repetition Of Withdrawal Method Of Intercourse?

I had unprotected sex two weeks ago but we used the pull out method and it was done correctly. Just to make sure I took the morning after pill 48 hours later and experienced heavy bleeding about 5 days later but it died down after a few days. I had unprotected sex again the following week with the pull out method and took the morning after pill for the second time and only experienced light bleeding this time. That same week we used the pull out method again 3 days later and I did not take the morning after pill. It seemed all times we had sex he pulled out correctly. But I am concerned because he wiped the sperm off with a napkin the second and third time we had sex and we had sex a few more times on the same day with him wiping the sperm off we waited about a half an hour before continuing to have more sex. What is the likely hood I am pregnant???
