Hello,I Had Anal Sex With My Boyfriend On The 10th

Hello,I had anal sex with my boyfriend on the 10th of April around 1am. He didn't have a condom on and he ejaculated in my butthole,my first concern is if it could have leaked close to my vaginal opening,I cleaned the outside of me very well,about an hour later we had sex again,with a condom,and he kept going in my butt and then back to my vagina,my second concern is if there could have been left over semen and he transferred it,I did take a plan B pill after 29 hours,but I am very scared. Am I pregnant?
