I normally have my period around the end of the month, 29 30 or 31. I bleed for about a week.
I had sex on November 7th, with no condom and took plan be on November 9th. I started to bleed a few days after, it wasn't too heavy and lasted about a week. I had sex again on December 6th and he came but I'm not sure it was in me... I don't know if the bleeding from plan be was my actually period, so I don't know if I should be on my period now or if my period is still regular, around the 30th.
Is there a possibility that I'm pregnant? Should I wait until the end of the month?

Yes, first you waited about two days to take plan B, the longer you wait the less effective it is, after about 72 hours after sex it has no effect.

Also it gave no protection at all for the second time you had sex. And there are plenty of sperm in the early fluids to make you pregnant.

Plan B is also for emergancy use, not regular use, so get on regular birth control and use a condom both if you do not want to become pregnant ( and even using both there is a slight chance still)

Plan B can make your period off for one to two months, even cause you to miss a period.
** but pregnancy can also.
So wait for about two weeks after the normal date of your period, and try a pregnancy test
