My friend currently told me that her and her boyfriend did the pull out method about 2 days ago. She's very nervous and scared that she might be pregnant and turned to me for help. How long should she wait to take a prenancy test if it's around the time of her period and she hasn't gotten it yet?

I would wait until the next missed period (if she misses it). Lucky for her she didn't have sex around the time she ovulated. Right now it is too early for her to be able to tell if she is pregnant with a HPT. Chances are slim that she is pregnant. Tell her that next time she decides to have sex to use protection, withdrawl is not a method of protection.
