In theory what you just siad makes no sense at all because you dont need a test if you know your pregnant as the first part suggests.
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.
Yes you can have a period still if you become pregnant before it, but the chances of that happening are slim. In a 28 day cycle ovulation takes place around day 14 -18 in the cycle and if the egg is not fertilized in that time the body will begin to prepare for a period. Sperm can stay alive in the uterus for 5-6 days, so if you had sex on day 12 of your cycle you could get pregnant very easily. Usually by the time you are ready to start your period all of this has all ready happened and the egg is no longer in the uterus and that is why you will have a period.
