I'm 18 and had unprotected sex, took a morning after pill 2 days after nd 7 days later I started my periods 2weeks earlier nd paused for a day then ble?

Pregnancy test. I would recommend you to get a pregnancy test. You can bleed during the pregnancy, which you would think was you normal period. Since you took morning after pills 48 hrs later, there is still a chance of getting pregnant.
