Can you get pregnant 7 days before fertilization and 2 day before ovaltion?

Yes. The window for conception for most women is open from just after you stop bleeding to 24 hours after the egg is released. This is because healthy sperm can survive in the female reproductive tract for more than a week. So in someone who has a 28 day cycle you can conceive anytime from around day 6 of your cycle through around day 16.
