Plan B anxiety

Hey guys! I know many will yell at me, but I need help! I have had sex a day after my period ended and took and plan b, had sex two days after and took it again. After the second time, I had withdrawal bleeding due to all the hormones for a couple of days (and it felt like a normal period). THEN I had sex again at the end of the month and took it again!!!! My question is, will my period be normal this month (October) or will it be messy? I am also extremely anxious about being pregnant. It has been 11 days since I took the last plan b.
