Question : Trying To Help my Cousin

Hey everyone! Sorry is this is TMI lol.

My cousin has sex with this guy last Saturday night and Sunday evening. He came in her 3 times .. back to back almost.

She was also ovulating the first two times that he did cum in here.

She took the Plan B pill Monday evening. Since she took the pill she said that she’s having really bad cramps and has been bleeding heavily?

Is there a chance that she can still get pregnant?

Note : She is a little heavy set if that makes a difference.
