Hello and welcome EmpowHer,
First of all, emergency contraception should only be taken in times of emergency, not every time you have sex. If you need birth control often then you should consider taking a monthly birth control instead.
The reason why you should not take EC frequently is because it contains hormones which disrupt your cycle. Since you took 2 in a matter of a few days, your cycle will be disrupted more than usual. You most likely will not get pregnant. At the same time there is no guarantee you will not, since you did not have a period after the last time you had sex.
At time all you can do it wait for your next period. If your period comes next month you are not pregnant. But if you also miss your next period in addition to this one, take a pregnancy test. You will need to wait until then for the test to be accurate.
