Can you full pregnant 3 to 4 days before your pirod and still have you pirod?

It is very unlikely that this will happen. In the typical 28 day cycle, you are only fertile on or around day 14. If you still have your period, it is a very good indication that you are not pregnant. Though some say it can happen, it is very rare and almost unheard of to get pregnant this close to your period and still have it.
