so me n my gf were doing it unprotected mindlessly (one thing just led to another) and then i pulled out b4 i ejaculated... Not sure if anything came out inside her but we were still doing it. Her period came 8 days ago (last Wednesday was the first sign of blood) and I know theres some infertile period I'm not sure if she's still in it. Should I make her take the pill or not worry about it at this point?

PLEASE READ:

OK so i posted this about an hour ago and almost everybody took this the wrong way. We did it this morning not 8 days ago. 8 days ago was when her period came. I had a plan B from 2 months ago just in case anything like this would happen. I use a condom everytime except for this morning in the heat of the moment. Now my question is should I just make her take the pill or is there a chance she wont get pregnant since ovulation is usually 14 days after she first bleeds and today is day 8???
